Module rustc_errors::diagnostic

Structs

• Diagnostic
• DiagnosticLocation
• DiagnosticStyledString
• IsLint
• SubDiagnostic
  A “sub”-diagnostic attached to a parent diagnostic. For example, a note attached to an error.
• SuggestionsDisabled
  Error type for Diagnostic’s suggestions field, indicating that .disable_suggestions() was called on the Diagnostic.

Enums

• DiagnosticArgValue
  Simplified version of FluentValue that can implement Encodable and Decodable. Converted to a FluentValue by the emitter to be used in diagnostic translation.
• StringPart

Traits

• AddToDiagnostic
  Trait implemented by error types. This should not be implemented manually. Instead, use #[derive(Subdiagnostic)] – see rustc_macros::Subdiagnostic.
• DecorateLint
  Trait implemented by lint types. This should not be implemented manually. Instead, use #[derive(LintDiagnostic)] – see rustc_macros::LintDiagnostic.
• IntoDiagnosticArg
  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

• DiagnosticArg
  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.
• DiagnosticArgName
  Name of a diagnostic argument.
