source§

fn emit_spanned_lint<S: Into<MultiSpan>>( &self, lint: &'static Lint, span: S, decorator: impl for<'a> DecorateLint<'a, ()> )

Emit a lint at span from a lint struct (some type that implements DecorateLint, typically generated by #[derive(LintDiagnostic)]).
source§

fn struct_span_lint<S: Into<MultiSpan>>( &self, lint: &'static Lint, span: S, msg: impl Into<DiagnosticMessage>, decorate: impl for<'a, 'b> FnOnce(&'b mut DiagnosticBuilder<'a, ()>) -> &'b mut DiagnosticBuilder<'a, ()> )

source§

fn fulfill_expectation(&self, expectation: LintExpectationId)

This function can be used to manually fulfill an expectation. This can be used for lints which contain several spans, and should be suppressed, if either location was marked with an expectation. Read more
