Structs

Enums

Traits

  • Trait implemented by error types. This should not be implemented manually. Instead, use #[derive(Subdiagnostic)] – see rustc_macros::Subdiagnostic.
  • Trait implemented by lint types. This should not be implemented manually. Instead, use #[derive(LintDiagnostic)] – see rustc_macros::LintDiagnostic.
  • Converts a value of a type into a DiagnosticArg (typically a field of an IntoDiagnostic struct). Implemented as a custom trait rather than From so that it is implemented on the type being converted rather than on DiagnosticArgValue, which enables types from other rustc_* crates to implement this.

Type Aliases

  • Simplified version of FluentArg that can implement Encodable and Decodable. Collection of DiagnosticArg are converted to FluentArgs (consuming the collection) at the start of diagnostic emission.
  • Name of a diagnostic argument.
