Enum aws_sdk_grafana::model::DataSourceType

#[non_exhaustive]
pub enum DataSourceType {
    AmazonOpensearchService,
    Athena,
    Cloudwatch,
    Prometheus,
    Redshift,
    Sitewise,
    Timestream,
    Xray,
    Unknown(UnknownVariantValue),
}

When writing a match expression against DataSourceType, 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 datasourcetype = unimplemented!();
match datasourcetype {
    DataSourceType::AmazonOpensearchService => { /* ... */ },
    DataSourceType::Athena => { /* ... */ },
    DataSourceType::Cloudwatch => { /* ... */ },
    DataSourceType::Prometheus => { /* ... */ },
    DataSourceType::Redshift => { /* ... */ },
    DataSourceType::Sitewise => { /* ... */ },
    DataSourceType::Timestream => { /* ... */ },
    DataSourceType::Xray => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

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