Source
type UnexpectedExprKind<'a> = Result<(Diag<'a>, bool), ErrorGuaranteed>;

  • Err is returned when the conversion process fails.

Aliased Type§

enum UnexpectedExprKind<'a> {
    Ok((Diag<'a>, bool)),
    Err(ErrorGuaranteed),
}

Variants§

§

Ok((Diag<'a>, bool))

Contains the success value

§

Err(ErrorGuaranteed)
