3/// When writing a match expression against `CannedAclForObjectsValue`, it is important to ensure
4/// your code is forward-compatible. That is, if a match arm handles a case for a
5/// feature that is supported by the service but has not been represented as an enum
6/// variant in a current version of SDK, your code should continue to work when you
7/// upgrade SDK to a future version in which the enum does include a variant for that
8/// feature.
9///
10/// Here is an example of how you can make a match expression forward-compatible:
11///
12/// ```text
13/// # let cannedaclforobjectsvalue = unimplemented!();
14/// match cannedaclforobjectsvalue {
15///     CannedAclForObjectsValue::AuthenticatedRead => { /* ... */ },
16///     CannedAclForObjectsValue::AwsExecRead => { /* ... */ },
17///     CannedAclForObjectsValue::BucketOwnerFullControl => { /* ... */ },
18///     CannedAclForObjectsValue::BucketOwnerRead => { /* ... */ },
19///     CannedAclForObjectsValue::None => { /* ... */ },
20///     CannedAclForObjectsValue::Private => { /* ... */ },
21///     CannedAclForObjectsValue::PublicRead => { /* ... */ },
22///     CannedAclForObjectsValue::PublicReadWrite => { /* ... */ },
23///     other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
24///     _ => { /* ... */ },
25/// }
26/// ```
27/// The above code demonstrates that when `cannedaclforobjectsvalue` represents
28/// `NewFeature`, the execution path will lead to the second last match arm,
29/// even though the enum does not contain a variant `CannedAclForObjectsValue::NewFeature`
30/// in the current version of SDK. The reason is that the variable `other`,
31/// created by the `@` operator, is bound to
32/// `CannedAclForObjectsValue::Unknown(UnknownVariantValue("NewFeature".to_owned()))`
33/// and calling `as_str` on it yields `"NewFeature"`.
34/// This match expression is forward-compatible when executed with a newer
35/// version of SDK where the variant `CannedAclForObjectsValue::NewFeature` is defined.
36/// Specifically, when `cannedaclforobjectsvalue` represents `NewFeature`,
37/// the execution path will hit the second last match arm as before by virtue of
38/// calling `as_str` on `CannedAclForObjectsValue::NewFeature` also yielding `"NewFeature"`.
39///
40/// Explicitly matching on the `Unknown` variant should
41/// be avoided for two reasons:
42/// - The inner data `UnknownVariantValue` is opaque, and no further information can be extracted.
43/// - It might inadvertently shadow other intended match arms.
