// This operation is not supported by directory buckets. Retrieves the
// PublicAccessBlock configuration for an Amazon S3 bucket. To use this operation,
// you must have the s3:GetBucketPublicAccessBlock permission. For more
// information about Amazon S3 permissions, see Specifying Permissions in a Policy (https://docs.aws.amazon.com/AmazonS3/latest/dev/using-with-s3-actions.html)
// . When Amazon S3 evaluates the PublicAccessBlock configuration for a bucket or
// an object, it checks the PublicAccessBlock configuration for both the bucket
// (or the bucket that contains the object) and the bucket owner's account. If the
// PublicAccessBlock settings are different between the bucket and the account,
// Amazon S3 uses the most restrictive combination of the bucket-level and
// account-level settings. For more information about when Amazon S3 considers a
// bucket or an object public, see The Meaning of "Public" (https://docs.aws.amazon.com/AmazonS3/latest/dev/access-control-block-public-access.html#access-control-block-public-access-policy-status)
