}Expand description
Trait implemented by error types. This should not be implemented manually. Instead, use
#[derive(Subdiagnostic)] – see rustc_macros::Subdiagnostic.
Required Methods§
sourcefn add_to_diagnostic_with<F>(self, diag: &mut Diagnostic, f: F)where
F: Fn(&mut Diagnostic, SubdiagnosticMessage) -> SubdiagnosticMessage,
fn add_to_diagnostic_with<F>(self, diag: &mut Diagnostic, f: F)where F: Fn(&mut Diagnostic, SubdiagnosticMessage) -> SubdiagnosticMessage,
Add a subdiagnostic to an existing diagnostic where f is invoked on every message used
(to optionally perform eager translation).
Provided Methods§
sourcefn add_to_diagnostic(self, diag: &mut Diagnostic)
fn add_to_diagnostic(self, diag: &mut Diagnostic)
Add a subdiagnostic to an existing diagnostic.
