Struct rustc_errors::DiagInner

source ·
pub struct DiagInner {
    pub(crate) level: Level,
    pub messages: Vec<(DiagMessage, Style)>,
    pub code: Option<ErrCode>,
    pub span: MultiSpan,
    pub children: Vec<Subdiag>,

Expand description

The main part of a diagnostic. Note that Diag, which wraps this type, is used for most operations, and should be used instead whenever possible. This type should only be used when Diag’s lifetime causes difficulties, e.g. when storing diagnostics within DiagCtxt.

Fields§

§level: Level§messages: Vec<(DiagMessage, Style)>§code: Option<ErrCode>§span: MultiSpan§children: Vec<Subdiag>§suggestions: Result<Vec<CodeSuggestion>, SuggestionsDisabled>§args: DiagArgMap§sort_span: Span

This is not used for highlighting or rendering any error message. Rather, it can be used as a sort key to sort a buffer of diagnostics. By default, it is the primary span of span if there is one. Otherwise, it is DUMMY_SP.

§is_lint: Option<IsLint>§emitted_at: DiagLocation

With -Ztrack_diagnostics enabled, we print where in rustc this error was emitted.
