3/// When writing a match expression against `OperationName`, 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 operationname = unimplemented!();
14/// match operationname {
15///     OperationName::LambdaInvoke => { /* ... */ },
16///     OperationName::S3ComputeObjectChecksum => { /* ... */ },
17///     OperationName::S3DeleteObjectTagging => { /* ... */ },
18///     OperationName::S3InitiateRestoreObject => { /* ... */ },
19///     OperationName::S3PutObjectAcl => { /* ... */ },
20///     OperationName::S3PutObjectCopy => { /* ... */ },
21///     OperationName::S3PutObjectLegalHold => { /* ... */ },
22///     OperationName::S3PutObjectRetention => { /* ... */ },
23///     OperationName::S3PutObjectTagging => { /* ... */ },
24///     OperationName::S3ReplicateObject => { /* ... */ },
25///     other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
26///     _ => { /* ... */ },
27/// }
28/// ```
29/// The above code demonstrates that when `operationname` represents
30/// `NewFeature`, the execution path will lead to the second last match arm,
31/// even though the enum does not contain a variant `OperationName::NewFeature`
32/// in the current version of SDK. The reason is that the variable `other`,
33/// created by the `@` operator, is bound to
34/// `OperationName::Unknown(UnknownVariantValue("NewFeature".to_owned()))`
35/// and calling `as_str` on it yields `"NewFeature"`.
36/// This match expression is forward-compatible when executed with a newer
37/// version of SDK where the variant `OperationName::NewFeature` is defined.
38/// Specifically, when `operationname` represents `NewFeature`,
39/// the execution path will hit the second last match arm as before by virtue of
40/// calling `as_str` on `OperationName::NewFeature` also yielding `"NewFeature"`.
41///
42/// Explicitly matching on the `Unknown` variant should
43/// be avoided for two reasons:
44/// - The inner data `UnknownVariantValue` is opaque, and no further information can be extracted.
45/// - It might inadvertently shadow other intended match arms.
