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.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
