// Applies an Amazon S3 bucket policy to an Amazon S3 bucket.
//
// Directory buckets - For directory buckets, you must make requests for this API
// operation to the Regional endpoint. These endpoints support path-style requests
// in the format https://s3express-control.region_code.amazonaws.com/bucket-name .
// Virtual-hosted-style requests aren't supported. For more information, see [Regional and Zonal endpoints]in
// the Amazon S3 User Guide.
//
// Permissions If you are using an identity other than the root user of the Amazon
// Web Services account that owns the bucket, the calling identity must both have
// the PutBucketPolicy permissions on the specified bucket and belong to the
// bucket owner's account in order to use this operation.
//
// If you don't have PutBucketPolicy permissions, Amazon S3 returns a 403 Access
// Denied error. If you have the correct permissions, but you're not using an
// identity that belongs to the bucket owner's account, Amazon S3 returns a 405
// Method Not Allowed error.
//
// To ensure that bucket owners don't inadvertently lock themselves out of their
// own buckets, the root principal in a bucket owner's Amazon Web Services account
// can perform the GetBucketPolicy , PutBucketPolicy , and DeleteBucketPolicy API
// actions, even if their bucket policy explicitly denies the root principal's
// access. Bucket owner root principals can only be blocked from performing these
// API actions by VPC endpoint policies and Amazon Web Services Organizations
// policies.
//
//   - General purpose bucket permissions - The s3:PutBucketPolicy permission is
//     required in a policy. For more information about general purpose buckets bucket
//     policies, see [Using Bucket Policies and User Policies]in the Amazon S3 User Guide.
//
//   - Directory bucket permissions - To grant access to this API operation, you
//     must have the s3express:PutBucketPolicy permission in an IAM identity-based
//     policy instead of a bucket policy. Cross-account access to this API operation
//     isn't supported. This operation can only be performed by the Amazon Web Services
//     account that owns the resource. For more information about directory bucket
//     policies and permissions, see [Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone]in the Amazon S3 User Guide.
//
// Example bucket policies  General purpose buckets example bucket policies - See [Bucket policy examples]
// in the Amazon S3 User Guide.
//
// Directory bucket example bucket policies - See [Example bucket policies for S3 Express One Zone] in the Amazon S3 User Guide.
//
// HTTP Host header syntax  Directory buckets - The HTTP Host header syntax is
// s3express-control.region.amazonaws.com .
//
// The following operations are related to PutBucketPolicy :
//
// [CreateBucket]
