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.

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.

pub fn as_str(&self) -> &str

Returns the &str value of the enum member.

pub const fn values() -> &'static [&'static str]

Returns all the &str representations of the enum members.

Trait Implementations

impl AsRef<str> for Event

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Event

fn clone(&self) -> Event

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Event

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<&str> for Event

fn from(s: &str) -> Event

Converts to this type from the input type.

impl FromStr for Event

type Err = Infallible

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Event, <Event as FromStr>::Err>
