Trait Subdiagnostic 

pub trait Subdiagnostic {
    // Required method
    fn add_to_diag<G: EmissionGuarantee>(self, diag: &mut Diag<'_, G>);
}

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

Required Methods

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

Add a subdiagnostic to an existing diagnostic.

Dyn Compatibility

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