Enum aws_sdk_amplifybackend::model::ServiceName

#[non_exhaustive]
pub enum ServiceName {
    S3,
    Unknown(UnknownVariantValue),
}

When writing a match expression against ServiceName, 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 servicename = unimplemented!();
match servicename {
    ServiceName::S3 => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

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

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.

S3

Unknown(UnknownVariantValue)

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

impl PartialEq<ServiceName> for ServiceName

fn eq(&self, other: &ServiceName) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<ServiceName> for ServiceName

fn partial_cmp(&self, other: &ServiceName) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
