Enum aws_sdk_sesv2::types::DkimStatus

#[non_exhaustive]
pub enum DkimStatus {
    Failed,
    NotStarted,
    Pending,
    Success,
    TemporaryFailure,
    Unknown(UnknownVariantValue),
}

When writing a match expression against DkimStatus, 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 dkimstatus = unimplemented!();
match dkimstatus {
    DkimStatus::Failed => { /* ... */ },
    DkimStatus::NotStarted => { /* ... */ },
    DkimStatus::Pending => { /* ... */ },
    DkimStatus::Success => { /* ... */ },
    DkimStatus::TemporaryFailure => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

The above code demonstrates that when dkimstatus represents NewFeature, the execution path will lead to the second last match arm, even though the enum does not contain a variant DkimStatus::NewFeature in the current version of SDK. The reason is that the variable other, created by the @ operator, is bound to DkimStatus::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 DkimStatus::NewFeature is defined. Specifically, when dkimstatus represents NewFeature, the execution path will hit the second last match arm as before by virtue of calling as_str on DkimStatus::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 DKIM authentication status of the identity. The status can be one of the following:

• PENDING – The verification process was initiated, but Amazon SES hasn't yet detected the DKIM records in the DNS configuration for the domain.

• SUCCESS – The verification process completed successfully.

• FAILED – The verification process failed. This typically occurs when Amazon SES fails to find the DKIM records in the DNS configuration of the domain.

• TEMPORARY_FAILURE – A temporary issue is preventing Amazon SES from determining the DKIM authentication status of the domain.

• NOT_STARTED – The DKIM verification process hasn't been initiated for the domain.

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.

Failed

NotStarted

Pending

Success

TemporaryFailure

Unknown(UnknownVariantValue)

Unknown contains new variants that have been added since this code was generated.
