Enum aws_sdk_devicefarm::model::RuleOperator

#[non_exhaustive]
pub enum RuleOperator {
    Contains,
    Equals,
    GreaterThan,
    GreaterThanOrEquals,
    In,
    LessThan,
    LessThanOrEquals,
    NotIn,
    Unknown(UnknownVariantValue),
}

When writing a match expression against RuleOperator, 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 ruleoperator = unimplemented!();
match ruleoperator {
    RuleOperator::Contains => { /* ... */ },
    RuleOperator::Equals => { /* ... */ },
    RuleOperator::GreaterThan => { /* ... */ },
    RuleOperator::GreaterThanOrEquals => { /* ... */ },
    RuleOperator::In => { /* ... */ },
    RuleOperator::LessThan => { /* ... */ },
    RuleOperator::LessThanOrEquals => { /* ... */ },
    RuleOperator::NotIn => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

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

Contains

Equals

GreaterThan

GreaterThanOrEquals

In

LessThan

LessThanOrEquals

NotIn

Unknown(UnknownVariantValue)

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