Trait Diagnostic 

pub trait Diagnostic<'a> {
    // Required method
    fn into_diag(self, dcx: DiagCtxtHandle<'a>, level: Level) -> Diag<'a>;
}

Trait implemented by error types. This is rarely implemented manually. Instead, use #[derive(Diagnostic)] – see rustc_macros::Diagnostic.

Required Methods

fn into_diag(self, dcx: DiagCtxtHandle<'a>, level: Level) -> Diag<'a>

Write out as a diagnostic out of DiagCtxt.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types
