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