+/// feature that is supported by the service but has not been represented as an enum
+/// variant in a current version of SDK, your code should continue to work when you
+/// upgrade SDK to a future version in which the enum does include a variant for that

+/// ```text

+/// match cachehealthmetricsconfig {
+///     CacheHealthMetricsConfig::Disabled => { /* ... */ },
+///     CacheHealthMetricsConfig::Enabled => { /* ... */ },
+///     other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
+///     _ => { /* ... */ },
+/// }
+/// ```
+/// The above code demonstrates that when `cachehealthmetricsconfig` represents
+/// `NewFeature`, the execution path will lead to the second last match arm,
+/// even though the enum does not contain a variant `CacheHealthMetricsConfig::NewFeature`
+/// in the current version of SDK. The reason is that the variable `other`,
+/// created by the `@` operator, is bound to
+/// `CacheHealthMetricsConfig::Unknown(UnknownVariantValue("NewFeature".to_owned()))`
+/// and calling `as_str` on it yields `"NewFeature"`.
+/// This match expression is forward-compatible when executed with a newer
+/// version of SDK where the variant `CacheHealthMetricsConfig::NewFeature` is defined.
+/// Specifically, when `cachehealthmetricsconfig` represents `NewFeature`,
+/// the execution path will hit the second last match arm as before by virtue of
+/// calling `as_str` on `CacheHealthMetricsConfig::NewFeature` also yielding `"NewFeature"`.
+///
+/// Explicitly matching on the `Unknown` variant should
+/// be avoided for two reasons:

+/// When writing a match expression against `DataSourceLevelMetricsConfig`, it is important to ensure
+/// your code is forward-compatible. That is, if a match arm handles a case for a
+/// feature that is supported by the service but has not been represented as an enum
+/// variant in a current version of SDK, your code should continue to work when you
+/// upgrade SDK to a future version in which the enum does include a variant for that
+/// feature.
+///
+/// Here is an example of how you can make a match expression forward-compatible:
+///
+/// ```text
+/// # let datasourcelevelmetricsconfig = unimplemented!();
+/// match datasourcelevelmetricsconfig {
+///     DataSourceLevelMetricsConfig::Disabled => { /* ... */ },
+///     DataSourceLevelMetricsConfig::Enabled => { /* ... */ },
+///     other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
+///     _ => { /* ... */ },
+/// }
+/// ```
+/// The above code demonstrates that when `datasourcelevelmetricsconfig` represents
+/// `NewFeature`, the execution path will lead to the second last match arm,
+/// even though the enum does not contain a variant `DataSourceLevelMetricsConfig::NewFeature`
+/// in the current version of SDK. The reason is that the variable `other`,
+/// created by the `@` operator, is bound to
+/// `DataSourceLevelMetricsConfig::Unknown(UnknownVariantValue("NewFeature".to_owned()))`
+/// and calling `as_str` on it yields `"NewFeature"`.
+/// This match expression is forward-compatible when executed with a newer
+/// version of SDK where the variant `DataSourceLevelMetricsConfig::NewFeature` is defined.
+/// Specifically, when `datasourcelevelmetricsconfig` represents `NewFeature`,

+/// When writing a match expression against `OperationLevelMetricsConfig`, it is important to ensure
+/// your code is forward-compatible. That is, if a match arm handles a case for a
+/// feature that is supported by the service but has not been represented as an enum
+/// variant in a current version of SDK, your code should continue to work when you
+/// upgrade SDK to a future version in which the enum does include a variant for that
+/// feature.
+///
+/// Here is an example of how you can make a match expression forward-compatible:
+///
+/// ```text
+/// # let operationlevelmetricsconfig = unimplemented!();
+/// match operationlevelmetricsconfig {
+///     OperationLevelMetricsConfig::Disabled => { /* ... */ },
+///     OperationLevelMetricsConfig::Enabled => { /* ... */ },
+///     other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
+///     _ => { /* ... */ },
+/// }
+/// ```
+/// The above code demonstrates that when `operationlevelmetricsconfig` represents
+/// `NewFeature`, the execution path will lead to the second last match arm,
+/// even though the enum does not contain a variant `OperationLevelMetricsConfig::NewFeature`
+/// in the current version of SDK. The reason is that the variable `other`,
+/// created by the `@` operator, is bound to
+/// `OperationLevelMetricsConfig::Unknown(UnknownVariantValue("NewFeature".to_owned()))`
+/// and calling `as_str` on it yields `"NewFeature"`.
+/// This match expression is forward-compatible when executed with a newer
+/// version of SDK where the variant `OperationLevelMetricsConfig::NewFeature` is defined.
+/// Specifically, when `operationlevelmetricsconfig` represents `NewFeature`,
+/// the execution path will hit the second last match arm as before by virtue of
+/// calling `as_str` on `OperationLevelMetricsConfig::NewFeature` also yielding `"NewFeature"`.
+///
+/// Explicitly matching on the `Unknown` variant should
+/// be avoided for two reasons:
+/// - The inner data `UnknownVariantValue` is opaque, and no further information can be extracted.

+// Code generated by software.amazon.smithy.rust.codegen.smithy-rs. DO NOT EDIT.
+
+/// When writing a match expression against `ResolverLevelMetricsConfig`, it is important to ensure
+/// your code is forward-compatible. That is, if a match arm handles a case for a
+/// feature that is supported by the service but has not been represented as an enum
+/// variant in a current version of SDK, your code should continue to work when you
+/// upgrade SDK to a future version in which the enum does include a variant for that
+/// feature.
+///
+/// Here is an example of how you can make a match expression forward-compatible:
+///
+/// ```text
+/// # let resolverlevelmetricsconfig = unimplemented!();
+/// match resolverlevelmetricsconfig {
+///     ResolverLevelMetricsConfig::Disabled => { /* ... */ },
+///     ResolverLevelMetricsConfig::Enabled => { /* ... */ },
+///     other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
+///     _ => { /* ... */ },
+/// }
+/// ```
+/// The above code demonstrates that when `resolverlevelmetricsconfig` represents
+/// `NewFeature`, the execution path will lead to the second last match arm,
+/// even though the enum does not contain a variant `ResolverLevelMetricsConfig::NewFeature`
+/// in the current version of SDK. The reason is that the variable `other`,
+/// created by the `@` operator, is bound to
+/// `ResolverLevelMetricsConfig::Unknown(UnknownVariantValue("NewFeature".to_owned()))`
+/// and calling `as_str` on it yields `"NewFeature"`.
+/// This match expression is forward-compatible when executed with a newer
+/// version of SDK where the variant `ResolverLevelMetricsConfig::NewFeature` is defined.
+/// Specifically, when `resolverlevelmetricsconfig` represents `NewFeature`,
+/// the execution path will hit the second last match arm as before by virtue of
+/// calling `as_str` on `ResolverLevelMetricsConfig::NewFeature` also yielding `"NewFeature"`.
