Enum aws_sdk_amplifybackend::model::DeliveryMethod

#[non_exhaustive]
pub enum DeliveryMethod {
    Email,
    Sms,
    Unknown(UnknownVariantValue),
}

When writing a match expression against DeliveryMethod, 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 deliverymethod = unimplemented!();
match deliverymethod {
    DeliveryMethod::Email => { /* ... */ },
    DeliveryMethod::Sms => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

The above code demonstrates that when deliverymethod represents NewFeature, the execution path will lead to the second last match arm, even though the enum does not contain a variant DeliveryMethod::NewFeature in the current version of SDK. The reason is that the variable other, created by the @ operator, is bound to DeliveryMethod::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 DeliveryMethod::NewFeature is defined. Specifically, when deliverymethod represents NewFeature, the execution path will hit the second last match arm as before by virtue of calling as_str on DeliveryMethod::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 type of verification message to send.

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.

Email

Sms

Unknown(UnknownVariantValue)

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