/// When writing a match expression against `ObjectOwnership`, it is important to ensure
/// your code is forward-compatible. That is, if a match arm handles a case for a
/// feature that is supported by the service but has not been represented as an enum
/// variant in a current version of SDK, your code should continue to work when you
/// upgrade SDK to a future version in which the enum does include a variant for that
/// feature.
///
/// Here is an example of how you can make a match expression forward-compatible:
///
/// ```text
/// # let objectownership = unimplemented!();
/// match objectownership {
///     ObjectOwnership::BucketOwnerEnforced => { /* ... */ },
///     ObjectOwnership::BucketOwnerPreferred => { /* ... */ },
///     ObjectOwnership::ObjectWriter => { /* ... */ },
///     other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
///     _ => { /* ... */ },
/// }
/// ```
/// The above code demonstrates that when `objectownership` represents
/// `NewFeature`, the execution path will lead to the second last match arm,
/// even though the enum does not contain a variant `ObjectOwnership::NewFeature`
/// in the current version of SDK. The reason is that the variable `other`,
/// created by the `@` operator, is bound to
/// `ObjectOwnership::Unknown(UnknownVariantValue("NewFeature".to_owned()))`
/// and calling `as_str` on it yields `"NewFeature"`.
/// This match expression is forward-compatible when executed with a newer
/// version of SDK where the variant `ObjectOwnership::NewFeature` is defined.
/// Specifically, when `objectownership` represents `NewFeature`,
/// the execution path will hit the second last match arm as before by virtue of
/// calling `as_str` on `ObjectOwnership::NewFeature` also yielding `"NewFeature"`.
///
/// Explicitly matching on the `Unknown` variant should
/// be avoided for two reasons:
/// - The inner data `UnknownVariantValue` is opaque, and no further information can be extracted.
/// - It might inadvertently shadow other intended match arms.
///
/// <p>The container element for object ownership for a bucket's ownership controls.</p>
/// <p>
/// <code>BucketOwnerPreferred</code> - Objects uploaded to the bucket change ownership to
/// the bucket owner if the objects are uploaded with the
/// <code>bucket-owner-full-control</code> canned ACL.</p>
/// <p>
/// <code>ObjectWriter</code> - The uploading account will own the object if the object is
/// uploaded with the <code>bucket-owner-full-control</code> canned ACL.</p>
/// <p>
/// <code>BucketOwnerEnforced</code> - Access control lists (ACLs) are disabled and no
/// longer affect permissions. The bucket owner automatically owns and has full control over
/// every object in the bucket. The bucket only accepts PUT requests that don't specify an ACL
/// or specify bucket owner full control ACLs (such as the predefined
/// <code>bucket-owner-full-control</code> canned ACL or a custom ACL in XML format that
/// grants the same permissions).</p>
/// <p>By default, <code>ObjectOwnership</code> is set to <code>BucketOwnerEnforced</code> and
/// ACLs are disabled. We recommend keeping ACLs disabled, except in uncommon use cases where
/// you must control access for each object individually. For more information about S3 Object
/// Ownership, see <a href="https://docs.aws.amazon.com/AmazonS3/latest/userguide/about-object-ownership.html">Controlling ownership of
/// objects and disabling ACLs for your bucket</a> in the
/// <i>Amazon S3 User Guide</i>. </p>
/// <note>
/// <p>This functionality is not supported for directory buckets. Directory buckets use the bucket owner enforced setting for S3 Object Ownership.</p>
