Required Methods

Return FluentBundle with localized diagnostics for the locale requested by the user. If no language was requested by the user then this will be None and fallback_fluent_bundle should be used.

Return FluentBundle with localized diagnostics for the default locale of the compiler. Used when the user has not requested a specific language or when a localized diagnostic is unavailable for the requested locale.

Provided Methods

Convert diagnostic arguments (a rustc internal type that exists to implement Encodable/Decodable) into FluentArgs which is necessary to perform translation.

Typically performed once for each diagnostic at the start of emit_diagnostic and then passed around as a reference thereafter.

Convert DiagnosticMessages to a string, performing translation if necessary.

Convert a DiagnosticMessage to a string, performing translation if necessary.
