Expand description

When writing a match expression against LanguageCode, 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 languagecode = unimplemented!();
match languagecode {
    LanguageCode::Aar => { /* ... */ },
    LanguageCode::Abk => { /* ... */ },
    LanguageCode::Afr => { /* ... */ },

    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

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

Specify the language, using an ISO 639-2 three-letter code in all capital letters. You can find a list of codes at: https://www.loc.gov/standards/iso639-2/php/code_list.php

Variants (Non-exhaustive)§

This enum is marked as 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.

§

Unknown(UnknownVariantValue)

👎Deprecated:

Don’t directly match on Unknown. See the docs on this enum for the correct way to handle unknown variants.

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