Expand description
When writing a match expression against TransformInstanceType
, 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 transforminstancetype = unimplemented!();
match transforminstancetype {
TransformInstanceType::MlC42Xlarge => { /* ... */ },
TransformInstanceType::MlC44Xlarge => { /* ... */ },
TransformInstanceType::MlC48Xlarge => { /* ... */ },
TransformInstanceType::MlC4Xlarge => { /* ... */ },
TransformInstanceType::MlC518Xlarge => { /* ... */ },
TransformInstanceType::MlC52Xlarge => { /* ... */ },
TransformInstanceType::MlC54Xlarge => { /* ... */ },
TransformInstanceType::MlC59Xlarge => { /* ... */ },
TransformInstanceType::MlC5Xlarge => { /* ... */ },
TransformInstanceType::MlG4Dn12Xlarge => { /* ... */ },
TransformInstanceType::MlG4Dn16Xlarge => { /* ... */ },
TransformInstanceType::MlG4Dn2Xlarge => { /* ... */ },
TransformInstanceType::MlG4Dn4Xlarge => { /* ... */ },
TransformInstanceType::MlG4Dn8Xlarge => { /* ... */ },
TransformInstanceType::MlG4DnXlarge => { /* ... */ },
TransformInstanceType::MlM410Xlarge => { /* ... */ },
TransformInstanceType::MlM416Xlarge => { /* ... */ },
TransformInstanceType::MlM42Xlarge => { /* ... */ },
TransformInstanceType::MlM44Xlarge => { /* ... */ },
TransformInstanceType::MlM4Xlarge => { /* ... */ },
TransformInstanceType::MlM512Xlarge => { /* ... */ },
TransformInstanceType::MlM524Xlarge => { /* ... */ },
TransformInstanceType::MlM52Xlarge => { /* ... */ },
TransformInstanceType::MlM54Xlarge => { /* ... */ },
TransformInstanceType::MlM5Large => { /* ... */ },
TransformInstanceType::MlM5Xlarge => { /* ... */ },
TransformInstanceType::MlP216Xlarge => { /* ... */ },
TransformInstanceType::MlP28Xlarge => { /* ... */ },
TransformInstanceType::MlP2Xlarge => { /* ... */ },
TransformInstanceType::MlP316Xlarge => { /* ... */ },
TransformInstanceType::MlP32Xlarge => { /* ... */ },
TransformInstanceType::MlP38Xlarge => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when transforminstancetype
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant TransformInstanceType::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
TransformInstanceType::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 TransformInstanceType::NewFeature
is defined.
Specifically, when transforminstancetype
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on TransformInstanceType::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.
