Expand description

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

Required Methods§

source

fn add_to_diag_with<G: EmissionGuarantee, F: SubdiagMessageOp<G>>( self, diag: &mut Diag<'_, G>, f: F )

Add a subdiagnostic to an existing diagnostic where f is invoked on every message used (to optionally perform eager translation).

Provided Methods§

source

fn add_to_diag<G: EmissionGuarantee>(self, diag: &mut Diag<'_, G>)

Add a subdiagnostic to an existing diagnostic.

Object Safety§

This trait is not object safe.
