Enum aws_sdk_machinelearning::model::EvaluationFilterVariable

#[non_exhaustive]
pub enum EvaluationFilterVariable {
    CreatedAt,
    DatasourceId,
    DataUri,
    IamUser,
    LastUpdatedAt,
    MlModelId,
    Name,
    Status,
    Unknown(UnknownVariantValue),
}

When writing a match expression against EvaluationFilterVariable, 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 evaluationfiltervariable = unimplemented!();
match evaluationfiltervariable {
    EvaluationFilterVariable::CreatedAt => { /* ... */ },
    EvaluationFilterVariable::DatasourceId => { /* ... */ },
    EvaluationFilterVariable::DataUri => { /* ... */ },
    EvaluationFilterVariable::IamUser => { /* ... */ },
    EvaluationFilterVariable::LastUpdatedAt => { /* ... */ },
    EvaluationFilterVariable::MlModelId => { /* ... */ },
    EvaluationFilterVariable::Name => { /* ... */ },
    EvaluationFilterVariable::Status => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

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

A list of the variables to use in searching or filtering Evaluation.

• CreatedAt - Sets the search criteria to Evaluation creation date.

• Status - Sets the search criteria to Evaluation status.

• Name - Sets the search criteria to the contents of Evaluation Name.

• IAMUser - Sets the search criteria to the user account that invoked an evaluation.

• MLModelId - Sets the search criteria to the Predictor that was evaluated.

• DataSourceId - Sets the search criteria to the DataSource used in evaluation.

• DataUri - Sets the search criteria to the data file(s) used in evaluation. The URL can identify either a file or an Amazon Simple Storage Service (Amazon S3) bucket or directory.

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.
