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