When writing a match expression against ExportableVolumeField, 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:

# let exportablevolumefield = unimplemented!();
match exportablevolumefield {
    ExportableVolumeField::AccountId => { /* ... */ },
    ExportableVolumeField::CurrentConfigurationVolumeBaselineIops => { /* ... */ },
    ExportableVolumeField::CurrentConfigurationVolumeBaselineThroughput => { /* ... */ },
    ExportableVolumeField::CurrentConfigurationVolumeBurstIops => { /* ... */ },
    ExportableVolumeField::CurrentConfigurationVolumeBurstThroughput => { /* ... */ },
    ExportableVolumeField::CurrentConfigurationVolumeSize => { /* ... */ },
    ExportableVolumeField::CurrentConfigurationVolumeType => { /* ... */ },
    ExportableVolumeField::CurrentMonthlyPrice => { /* ... */ },
    ExportableVolumeField::CurrentPerformanceRisk => { /* ... */ },
    ExportableVolumeField::Finding => { /* ... */ },
    ExportableVolumeField::LastRefreshTimestamp => { /* ... */ },
    ExportableVolumeField::LookbackPeriodInDays => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsConfigurationVolumeBaselineIops => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsConfigurationVolumeBaselineThroughput => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsConfigurationVolumeBurstIops => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsConfigurationVolumeBurstThroughput => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsConfigurationVolumeSize => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsConfigurationVolumeType => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsEstimatedMonthlySavingsCurrency => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsEstimatedMonthlySavingsValue => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsMonthlyPrice => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsPerformanceRisk => { /* ... */ },
    ExportableVolumeField::RecommendationOptionsSavingsOpportunityPercentage => { /* ... */ },
    ExportableVolumeField::UtilizationMetricsVolumeReadBytesPerSecondMaximum => { /* ... */ },
    ExportableVolumeField::UtilizationMetricsVolumeReadOpsPerSecondMaximum => { /* ... */ },
    ExportableVolumeField::UtilizationMetricsVolumeWriteBytesPerSecondMaximum => { /* ... */ },
    ExportableVolumeField::UtilizationMetricsVolumeWriteOpsPerSecondMaximum => { /* ... */ },
    ExportableVolumeField::VolumeArn => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

The above code demonstrates that when exportablevolumefield represents NewFeature, the execution path will lead to the second last match arm, even though the enum does not contain a variant ExportableVolumeField::NewFeature in the current version of SDK. The reason is that the variable other, created by the @ operator, is bound to ExportableVolumeField::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 ExportableVolumeField::NewFeature is defined. Specifically, when exportablevolumefield represents NewFeature, the execution path will hit the second last match arm as before by virtue of calling as_str on ExportableVolumeField::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.
• It might inadvertently shadow other intended match arms.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
