        object_ (str):
            Required. The name of the object to read.
        generation (int):
            Optional. If present, selects a specific

        read_offset (int):
            Optional. The offset for the first byte to return in the
            read, relative to the start of the object.

            A negative ``read_offset`` value is interpreted as the
            number of bytes back from the end of the object to be
            returned. For example, if an object's length is ``15``
            bytes, a ``ReadObjectRequest`` with ``read_offset`` = ``-5``
            and ``read_limit`` = ``3`` would return bytes ``10`` through
            ``12`` of the object. Requesting a negative offset with
            magnitude larger than the size of the object returns the
            entire object.
        read_limit (int):
            Optional. The maximum number of ``data`` bytes the server is
            allowed to return in the sum of all ``Object`` messages. A
            ``read_limit`` of zero indicates that there is no limit, and
            a negative ``read_limit`` causes an error.

            If the stream returns fewer bytes than allowed by the
            ``read_limit`` and no error occurred, the stream includes
            all data from the ``read_offset`` to the end of the
            resource.

            A negative read_offset value is interpreted as the number of
            bytes back from the end of the object to be returned. For

            ``ReadObjectRequest`` with ``read_offset`` = -5 and
            ``read_length`` = 3 would return bytes 10 through 12 of the

            than the size of the object returns the entire object. A
            ``read_offset`` larger than the size of the object results
            in an ``OutOfRange`` error.

            1,000 items, whichever is smaller.
        page_token (str):
            Optional. A previously-returned page token
            representing part of the larger set of results
            to view.
        delimiter (str):
            Optional. If set, returns results in a directory-like mode.
            ``items`` contains only objects whose names, aside from the
            ``prefix``, do not contain ``delimiter``. Objects whose
            names, aside from the ``prefix``, contain ``delimiter`` has
            their name, truncated after the ``delimiter``, returned in
            ``prefixes``. Duplicate ``prefixes`` are omitted.
        include_trailing_delimiter (bool):
            Optional. If true, objects that end in exactly one instance
            of ``delimiter`` has their metadata included in ``items`` in
            addition to ``prefixes``.
        prefix (str):
            Optional. Filter results to objects whose
            names begin with this prefix.
        versions (bool):
            Optional. If ``true``, lists all versions of an object as
            distinct results.
        read_mask (google.protobuf.field_mask_pb2.FieldMask):
            Mask specifying which fields to read from each result. If no
            mask is specified, defaults to all fields except
            ``items.acl`` and ``items.owner``. ``*`` might be used to
            mean all fields.

            This field is a member of `oneof`_ ``_read_mask``.
        lexicographic_start (str):
            Optional. Filter results to objects whose names are
            lexicographically equal to or after ``lexicographic_start``.
            If ``lexicographic_end`` is also set, the objects listed
            have names between ``lexicographic_start`` (inclusive) and
            ``lexicographic_end`` (exclusive).
        lexicographic_end (str):
            Optional. Filter results to objects whose names are
            lexicographically before ``lexicographic_end``. If
            ``lexicographic_start`` is also set, the objects listed have
            names between ``lexicographic_start`` (inclusive) and
            ``lexicographic_end`` (exclusive).
        soft_deleted (bool):
            Optional. If true, only list all soft-deleted
            versions of the object. Soft delete policy is
            required to set this option.
        include_folders_as_prefixes (bool):
            Optional. If true, includes folders and managed folders
            (besides objects) in the returned ``prefixes``. Requires
            ``delimiter`` to be set to '/'.
        match_glob (str):
            Optional. Filter results to objects and prefixes that match
            this glob pattern. See `List objects using
            glob <https://cloud.google.com/storage/docs/json_api/v1/objects/list#list-objects-and-prefixes-using-glob>`__
            for the full syntax.
        filter (str):
            Optional. An expression used to filter the returned objects
            by the ``context`` field. For the full syntax, see `Filter
            objects by contexts
            syntax <https://cloud.google.com/storage/docs/listing-objects#filter-by-object-contexts-syntax>`__.
            If a ``delimiter`` is set, the returned ``prefixes`` are
            exempt from this filter.

            the `Naming
            Guidelines <https://cloud.google.com/storage/docs/objects#naming>`__.
            Example: ``test.txt`` The ``name`` field by itself does not
            uniquely identify a Cloud Storage object. A Cloud Storage
            object is uniquely identified by the tuple of (bucket,
            object, generation).
        destination_bucket (str):
            Required. Immutable. The name of the bucket
            containing the destination object.
        destination_kms_key (str):
            Optional. The name of the Cloud KMS key that
            is used to encrypt the destination object. The
            Cloud KMS key must be located in same location
            as the object. If the parameter is not
            specified, the request uses the destination
            bucket's default encryption key, if any, or else
            the Google-managed encryption key.
        destination (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Object):
            Optional. Properties of the destination, post-rewrite
            object. The ``name``, ``bucket`` and ``kms_key`` fields must
            not be populated (these values are specified in the
            ``destination_name``, ``destination_bucket``, and
            ``destination_kms_key`` fields). If ``destination`` is

            metadata; otherwise the destination object's metadata is
            copied from the source object.
        source_bucket (str):
            Required. Name of the bucket in which to find
            the source object.
        source_object (str):
            Required. Name of the source object.
        source_generation (int):
            Optional. If present, selects a specific
            revision of the source object (as opposed to the
            latest version, the default).
        rewrite_token (str):
            Optional. Include this field (from the
            previous rewrite response) on each rewrite
            request after the first one, until the rewrite
            response 'done' flag is true. Calls that provide
            a rewriteToken can omit all other request
            fields, but if included those fields must match
            the values provided in the first rewrite
            request.
        destination_predefined_acl (str):
            Optional. Apply a predefined set of access controls to the
            destination object. Valid values are ``authenticatedRead``,
            ``bucketOwnerFullControl``, ``bucketOwnerRead``,
            ``private``, ``projectPrivate``, or ``publicRead``.

            the object's current generation matches the
            given value. Setting to 0 makes the operation

            given value. If no live object exists, the
            precondition fails. Setting to 0 makes the

            matches the given value.

            This field is a member of `oneof`_ ``_if_source_metageneration_not_match``.
        max_bytes_rewritten_per_call (int):
            Optional. The maximum number of bytes that are rewritten per
            rewrite request. Most callers shouldn't need to specify this
            parameter - it is primarily in place to support testing. If
            specified the value must be an integral multiple of 1 MiB
            (1048576). Also, this only applies to requests where the
            source and destination span locations and/or storage
            classes. Finally, this value must not change across rewrite
            calls else you'll get an error that the ``rewriteToken`` is
            invalid.
        copy_source_encryption_algorithm (str):
            Optional. The algorithm used to encrypt the
            source object, if any. Used if the source object
            was encrypted with a Customer-Supplied
            Encryption Key.
        copy_source_encryption_key_bytes (bytes):
            Optional. The raw bytes (not base64-encoded)
            AES-256 encryption key used to encrypt the
            source object, if it was encrypted with a
            Customer-Supplied Encryption Key.
        copy_source_encryption_key_sha256_bytes (bytes):
            Optional. The raw bytes (not base64-encoded)
            SHA256 hash of the encryption key used to
            encrypt the source object, if it was encrypted
            with a Customer-Supplied Encryption Key.
        common_object_request_params (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.CommonObjectRequestParams):
            Optional. A set of parameters common to
            Storage API requests concerning an object.
        object_checksums (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.ObjectChecksums):
            Optional. The checksums of the complete
            object. This is used to validate the destination
            object after rewriting.

            of ``projects/{projectIdentifier}``. ``{projectIdentifier}``
            can be the project ID or project number. Output values are
            always in the project number format.
        metageneration (int):
            Output only. The metadata generation of this
            bucket.
        location (str):
            Immutable. The location of the bucket. Object data for
            objects in the bucket resides in physical storage within
            this region. Defaults to ``US``. Attempting to update this
            field after the bucket is created results in an error.
        location_type (str):
            Output only. The location type of the bucket
            (region, dual-region, multi-region, etc).
        storage_class (str):
            Optional. The bucket's default storage class, used whenever
            no storageClass is specified for a newly-created object.
            This defines how objects in the bucket are stored and
            determines the SLA and the cost of storage. If this value is
            not specified when the bucket is created, it defaults to
            ``STANDARD``. For more information, see `Storage
            classes <https://developers.google.com/storage/docs/storage-classes>`__.
        rpo (str):
            Optional. The recovery point objective for cross-region
            replication of the bucket. Applicable only for dual- and
            multi-region buckets. ``DEFAULT`` uses default replication.
            ``ASYNC_TURBO`` enables turbo replication, valid for
            dual-region buckets only. If rpo is not specified when the
            bucket is created, it defaults to ``DEFAULT``. For more
            information, see `Turbo
            replication <https://cloud.google.com/storage/docs/availability-durability#turbo-replication>`__.
        acl (MutableSequence[googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.BucketAccessControl]):
            Optional. Access controls on the bucket. If
            ``iam_config.uniform_bucket_level_access`` is enabled on
            this bucket, requests to set, read, or modify acl is an
            error.
        default_object_acl (MutableSequence[googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.ObjectAccessControl]):
            Optional. Default access controls to apply to new objects
            when no ACL is provided. If
            ``iam_config.uniform_bucket_level_access`` is enabled on
            this bucket, requests to set, read, or modify acl is an
            error.
        lifecycle (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.Lifecycle):
            Optional. The bucket's lifecycle configuration. See
            `Lifecycle
            Management <https://developers.google.com/storage/docs/lifecycle>`__
            for more information.
        create_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. The creation time of the bucket.
        cors (MutableSequence[googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.Cors]):
            Optional. The bucket's
            `CORS <https://www.w3.org/TR/cors/>`__ configuration.
        update_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. The modification time of the
            bucket.
        default_event_based_hold (bool):
            Optional. The default value for event-based
            hold on newly created objects in this bucket.
            Event-based hold is a way to retain objects
            indefinitely until an event occurs, signified by
            the hold's release. After being released, such
            objects are subject to bucket-level retention
            (if any).  One sample use case of this flag is
            for banks to hold loan documents for at least 3
            years after loan is paid in full. Here,
            bucket-level retention is 3 years and the event
            is loan being paid in full. In this example,
            these objects are held intact for any number of
            years until the event has occurred (event-based
            hold on the object is released) and then 3 more
            years after that. That means retention duration
            of the objects begins from the moment
            event-based hold transitioned from true to
            false.  Objects under event-based hold cannot be
            deleted, overwritten or archived until the hold
            is removed.
        labels (MutableMapping[str, str]):
            Optional. User-provided labels, in key/value
            pairs.
        website (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.Website):
            Optional. The bucket's website config, controlling how the
            service behaves when accessing bucket contents as a web
            site. See the `Static website
            examples <https://cloud.google.com/storage/docs/static-website>`__
            for more information.
        versioning (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.Versioning):
            Optional. The bucket's versioning
            configuration.
        logging (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.Logging):
            Optional. The bucket's logging config, which
            defines the destination bucket and name prefix
            (if any) for the current bucket's logs.
        owner (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Owner):
            Output only. The owner of the bucket. This is
            always the project team's owner group.
        encryption (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.Encryption):
            Optional. Encryption config for a bucket.
        billing (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.Billing):
            Optional. The bucket's billing configuration.
        retention_policy (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.RetentionPolicy):
            Optional. The bucket's retention policy. The retention
            policy enforces a minimum retention time for all objects
            contained in the bucket, based on their creation time. Any
            attempt to overwrite or delete objects younger than the
            retention period results in a ``PERMISSION_DENIED`` error.
            An unlocked retention policy can be modified or removed from
            the bucket via a storage.buckets.update operation. A locked
            retention policy cannot be removed or shortened in duration
            for the lifetime of the bucket. Attempting to remove or
            decrease period of a locked retention policy results in a
            ``PERMISSION_DENIED`` error.
        iam_config (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.IamConfig):
            Optional. The bucket's IAM configuration.
        satisfies_pzs (bool):
            Optional. Reserved for future use.
        custom_placement_config (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.CustomPlacementConfig):
            Optional. Configuration that, if present, specifies the data
            placement for a `configurable
            dual-region <https://cloud.google.com/storage/docs/locations#location-dr>`__.
        autoclass (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.Autoclass):
            Optional. The bucket's Autoclass
            configuration. If there is no configuration, the
            Autoclass feature is disabled and has no effect
            on the bucket.
        hierarchical_namespace (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.HierarchicalNamespace):
            Optional. The bucket's hierarchical namespace
            configuration. If there is no configuration, the
            hierarchical namespace feature is disabled and
            has no effect on the bucket.
        soft_delete_policy (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.SoftDeletePolicy):
            Optional. The bucket's soft delete policy.
            The soft delete policy prevents soft-deleted
            objects from being permanently deleted.
        object_retention (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.ObjectRetention):
            Optional. The bucket's object retention
            configuration. Must be enabled before objects in
            the bucket might have retention configured.
        ip_filter (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Bucket.IpFilter):
            Optional. The bucket's IP filter

            Example: ``test.txt`` The ``name`` field by itself does not
            uniquely identify a Cloud Storage object. A Cloud Storage
            object is uniquely identified by the tuple of (bucket,
            object, generation).
        bucket (str):
            Immutable. The name of the bucket containing
            this object.
        etag (str):

            and generation. This field is output only, and
            only set for deleted objects in HNS buckets.

            This field is a member of `oneof`_ ``_restore_token``.
        metageneration (int):

            this generation of this object. Used for
            preconditions and for detecting changes in
            metadata. A metageneration number is only
            meaningful in the context of a particular
            generation of a particular object.
        storage_class (str):
            Optional. Storage class of the object.
        size (int):

        cache_control (str):

            $5.2 <https://tools.ietf.org/html/rfc7234#section-5.2>`__.
            If omitted, and the object is accessible to all anonymous

        acl (MutableSequence[googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.ObjectAccessControl]):

            ``iam_config.uniform_bucket_level_access`` is enabled on the
            parent bucket, requests to set, read, or modify acl is an

        content_type (str):
            Optional. Content-Type of the object data, matching `RFC

            If an object is stored without a Content-Type, it is served
            as ``application/octet-stream``.
        create_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. The creation time of the object.
        component_count (int):
            Output only. Number of underlying components
            that make up this object. Components are
            accumulated by compose operations.
        checksums (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.ObjectChecksums):
            Output only. Hashes for the data part of this
            object. This field is used for output only and
            is silently ignored if provided in requests. The
            checksums of the complete object regardless of
            data range. If the object is downloaded in full,
            the client should compute one of these checksums
            over the downloaded object and compare it
            against the value provided here.
        update_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. The modification time of the
            object metadata. Set initially to object
            creation time and then updated whenever any
            metadata of the object changes. This includes
            changes made by a requester, such as modifying
            custom metadata, as well as changes made by
            Cloud Storage on behalf of a requester, such as
            changing the storage class based on an Object
            Lifecycle Configuration.
        kms_key (str):
            Optional. Cloud KMS Key used to encrypt this
            object, if the object is encrypted by such a
            key.
        update_storage_class_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. The time at which the object's storage class
            was last changed. When the object is initially created, it
            is set to ``time_created``.
        temporary_hold (bool):
            Optional. Whether an object is under
            temporary hold. While this flag is set to true,
            the object is protected against deletion and
            overwrites.  A common use case of this flag is
            regulatory investigations where objects need to
            be retained while the investigation is ongoing.
            Note that unlike event-based hold, temporary
            hold does not impact retention expiration time
            of an object.
        retention_expire_time (google.protobuf.timestamp_pb2.Timestamp):
            Optional. A server-determined value that
            specifies the earliest time that the object's
            retention period expires. Note 1: This field is
            not provided for objects with an active
            event-based hold, since retention expiration is
            unknown until the hold is removed. Note 2: This
            value can be provided even when temporary hold
            is set (so that the user can reason about policy
            without having to first unset the temporary
            hold).
        metadata (MutableMapping[str, str]):
            Optional. User-provided metadata, in
            key/value pairs.
        contexts (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.ObjectContexts):
            Optional. User-defined or system-defined
            object contexts. Each object context is a
            key-payload pair, where the key provides the
            identification and the payload holds the
            associated value and additional metadata.
        event_based_hold (bool):
            Whether an object is under event-based hold. An event-based
            hold is a way to force the retention of an object until
            after some event occurs. Once the hold is released by
            explicitly setting this field to ``false``, the object
            becomes subject to any bucket-level retention policy, except
            that the retention duration is calculated from the time the
            event based hold was lifted, rather than the time the object
            was created.

            In a ``WriteObject`` request, not setting this field implies
            that the value should be taken from the parent bucket's
            ``default_event_based_hold`` field. In a response, this
            field is always set to ``true`` or ``false``.

            This field is a member of `oneof`_ ``_event_based_hold``.
        owner (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Owner):
            Output only. The owner of the object. This is
            always the uploader of the object.
        customer_encryption (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.CustomerEncryption):
            Optional. Metadata of customer-supplied
            encryption key, if the object is encrypted by
            such a key.
        custom_time (google.protobuf.timestamp_pb2.Timestamp):
            Optional. A user-specified timestamp set on
            an object.
        soft_delete_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. This is the time when the object became
            soft-deleted.

            Soft-deleted objects are only accessible if a
            soft_delete_policy is enabled. Also see
            ``hard_delete_time``.

            This field is a member of `oneof`_ ``_soft_delete_time``.
        hard_delete_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. The time when the object is permanently
            deleted.

            Only set when an object becomes soft-deleted with a
            ``soft_delete_policy``. Otherwise, the object is not
            accessible.

            This field is a member of `oneof`_ ``_hard_delete_time``.
        retention (googlecloudsdk.generated_clients.gapic_clients.storage_v2.types.Object.Retention):
            Optional. Retention configuration of this
