}Expand description
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::CurrentConfigurationRootVolume => { /* ... */ },
ExportableVolumeField::CurrentConfigurationVolumeBaselineIops => { /* ... */ },
ExportableVolumeField::CurrentConfigurationVolumeBaselineThroughput => { /* ... */ },
ExportableVolumeField::CurrentConfigurationVolumeBurstIops => { /* ... */ },
ExportableVolumeField::CurrentConfigurationVolumeBurstThroughput => { /* ... */ },
ExportableVolumeField::CurrentConfigurationVolumeSize => { /* ... */ },
ExportableVolumeField::CurrentConfigurationVolumeType => { /* ... */ },
ExportableVolumeField::CurrentMonthlyPrice => { /* ... */ },
ExportableVolumeField::CurrentPerformanceRisk => { /* ... */ },
ExportableVolumeField::EffectiveRecommendationPreferencesSavingsEstimationMode => { /* ... */ },
ExportableVolumeField::Finding => { /* ... */ },
ExportableVolumeField::LastRefreshTimestamp => { /* ... */ },
ExportableVolumeField::LookbackPeriodInDays => { /* ... */ },
ExportableVolumeField::RecommendationOptionsConfigurationVolumeBaselineIops => { /* ... */ },
ExportableVolumeField::RecommendationOptionsConfigurationVolumeBaselineThroughput => { /* ... */ },
ExportableVolumeField::RecommendationOptionsConfigurationVolumeBurstIops => { /* ... */ },
ExportableVolumeField::RecommendationOptionsConfigurationVolumeBurstThroughput => { /* ... */ },
ExportableVolumeField::RecommendationOptionsConfigurationVolumeSize => { /* ... */ },
ExportableVolumeField::RecommendationOptionsConfigurationVolumeType => { /* ... */ },
ExportableVolumeField::RecommendationOptionsEstimatedMonthlySavingsCurrency => { /* ... */ },
ExportableVolumeField::RecommendationOptionsEstimatedMonthlySavingsCurrencyAfterDiscounts => { /* ... */ },
ExportableVolumeField::RecommendationOptionsEstimatedMonthlySavingsValue => { /* ... */ },
ExportableVolumeField::RecommendationOptionsEstimatedMonthlySavingsValueAfterDiscounts => { /* ... */ },
ExportableVolumeField::RecommendationOptionsMonthlyPrice => { /* ... */ },
ExportableVolumeField::RecommendationOptionsPerformanceRisk => { /* ... */ },
ExportableVolumeField::RecommendationOptionsSavingsOpportunityAfterDiscountsPercentage => { /* ... */ },
ExportableVolumeField::RecommendationOptionsSavingsOpportunityPercentage => { /* ... */ },
ExportableVolumeField::RootVolume => { /* ... */ },
ExportableVolumeField::Tags => { /* ... */ },
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
UnknownVariantValueis opaque, and no further information can be extracted. - It might inadvertently shadow other intended match arms.
