3/// When writing a match expression against `S3DataType`, 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 s3datatype = unimplemented!();
14/// match s3datatype {
15///     S3DataType::AugmentedManifestFile => { /* ... */ },
16///     S3DataType::Converse => { /* ... */ },
17///     S3DataType::ManifestFile => { /* ... */ },
18///     S3DataType::S3Prefix => { /* ... */ },
19///     other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
20///     _ => { /* ... */ },
21/// }
22/// ```
23/// The above code demonstrates that when `s3datatype` represents
24/// `NewFeature`, the execution path will lead to the second last match arm,
25/// even though the enum does not contain a variant `S3DataType::NewFeature`
26/// in the current version of SDK. The reason is that the variable `other`,
27/// created by the `@` operator, is bound to
28/// `S3DataType::Unknown(UnknownVariantValue("NewFeature".to_owned()))`
29/// and calling `as_str` on it yields `"NewFeature"`.
30/// This match expression is forward-compatible when executed with a newer
31/// version of SDK where the variant `S3DataType::NewFeature` is defined.
32/// Specifically, when `s3datatype` represents `NewFeature`,
33/// the execution path will hit the second last match arm as before by virtue of
34/// calling `as_str` on `S3DataType::NewFeature` also yielding `"NewFeature"`.
35///
36/// Explicitly matching on the `Unknown` variant should
37/// be avoided for two reasons:
38/// - The inner data `UnknownVariantValue` is opaque, and no further information can be extracted.
39/// - It might inadvertently shadow other intended match arms.
40///
