Expand description
When writing a match expression against Event
, 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 event = unimplemented!();
match event {
Event::S3IntelligentTiering => { /* ... */ },
Event::S3LifecycleExpiration => { /* ... */ },
Event::S3LifecycleExpirationDelete => { /* ... */ },
Event::S3LifecycleExpirationDeleteMarkerCreated => { /* ... */ },
Event::S3LifecycleTransition => { /* ... */ },
Event::S3ObjectAclPut => { /* ... */ },
Event::S3ObjectCreated => { /* ... */ },
Event::S3ObjectCreatedCompleteMultipartUpload => { /* ... */ },
Event::S3ObjectCreatedCopy => { /* ... */ },
Event::S3ObjectCreatedPost => { /* ... */ },
Event::S3ObjectCreatedPut => { /* ... */ },
Event::S3ObjectRemoved => { /* ... */ },
Event::S3ObjectRemovedDelete => { /* ... */ },
Event::S3ObjectRemovedDeleteMarkerCreated => { /* ... */ },
Event::S3ObjectRestore => { /* ... */ },
Event::S3ObjectRestoreCompleted => { /* ... */ },
Event::S3ObjectRestoreDelete => { /* ... */ },
Event::S3ObjectRestorePost => { /* ... */ },
Event::S3ObjectTagging => { /* ... */ },
Event::S3ObjectTaggingDelete => { /* ... */ },
Event::S3ObjectTaggingPut => { /* ... */ },
Event::S3ReducedRedundancyLostObject => { /* ... */ },
Event::S3Replication => { /* ... */ },
Event::S3ReplicationOperationFailedReplication => { /* ... */ },
Event::S3ReplicationOperationMissedThreshold => { /* ... */ },
Event::S3ReplicationOperationNotTracked => { /* ... */ },
Event::S3ReplicationOperationReplicatedAfterThreshold => { /* ... */ },
other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
_ => { /* ... */ },
}
The above code demonstrates that when event
represents
NewFeature
, the execution path will lead to the second last match arm,
even though the enum does not contain a variant Event::NewFeature
in the current version of SDK. The reason is that the variable other
,
created by the @
operator, is bound to
Event::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 Event::NewFeature
is defined.
Specifically, when event
represents NewFeature
,
the execution path will hit the second last match arm as before by virtue of
calling as_str
on Event::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.
The bucket event for which to send notifications.
