Types of subdiagnostics that can be created using attributes

Variants

Label

#[label(...)]

Note

#[note(...)]

NoteOnce

#[note_once(...)]

Help

#[help(...)]

HelpOnce

#[help_once(...)]

Warn

#[warning(...)]

Suggestion

#[suggestion{,_short,_hidden,_verbose}]

Fields

suggestion_kind: SuggestionKind

applicability: Option<(Applicability, Span)>

code_field: Ident

Identifier for variable used for formatted code, e.g. ___code_0. Enables separation of formatting and diagnostic emission so that arg calls can happen in-between..

code_init: TokenStream

Initialization logic for code_field’s variable, e.g. let __formatted_code = /* whatever */;

MultipartSuggestion

#[multipart_suggestion{,_short,_hidden,_verbose}]

Fields

suggestion_kind: SuggestionKind

applicability: Option<(Applicability, Span)>
