-- Returns the Region the bucket resides in. You set the bucket\'s Region
-- using the @LocationConstraint@ request parameter in a @CreateBucket@
-- request. For more information, see
-- <https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateBucket.html CreateBucket>.
--
-- To use this implementation of the operation, you must be the bucket
-- owner.
--
-- To use this API against an access point, provide the alias of the access
-- point in place of the bucket name.
--
-- The following operations are related to @GetBucketLocation@:
