 * @template TMethod The type of the method to execute.
 *
 * @param method The method used to generate the values.
 * @param args The arguments used to call the method.
 * @param options The optional options used to configure this method.
 * @param options.startTime The time this execution stared. Defaults to `new Date().getTime()`.
 * @param options.maxTime The time in milliseconds this method may take before throwing an error. Defaults to `50`.
 * @param options.maxRetries The total number of attempts to try before throwing an error. Defaults to `50`.
 * @param options.currentIterations The current attempt. Defaults to `0`.
 * @param options.exclude The value or values that should be excluded/skipped. Defaults to `[]`.
 * @param options.compare The function used to determine whether a value was already returned. Defaults to check the existence of the key.
 * @param options.store The store of unique entries. Defaults to `GLOBAL_UNIQUE_STORE`.
