sive of a range of use cases as
[pin-project] does. If your use case is not already covered, please use
[pin-project].

### Different: No proc-macro related dependencies

This is the **only** reason to use this crate. However, **if you already
have proc-macro related dependencies in your crate's dependency graph, there
is no benefit from using this crate.** (Note: There is almost no difference
in the amount of code generated between [pin-project] and pin-project-lite.)

### Different: No useful error messages

This macro does not handle any invalid input. So error messages are not to
be useful in most cases. If you do need useful error messages, then upon
error you can pass the same input to [pin-project] to receive a helpful
description of the compile error.

### Different: No support for custom Unpin implementation

pin-project supports this by [`UnsafeUnpin`][unsafe-unpin]. (`!Unpin` is supported by both [pin-project][not-unpin] and [pin-project-lite][not-unpin-lite].)

### Different: No support for tuple structs and tuple variants

pin-project supports this.
