Type Alias rustc_errors::PErr

pub type PErr<'a> = DiagnosticBuilder<'a>;

Aliased Type

struct PErr<'a> {
    state: DiagnosticBuilderState<'a>,
    diagnostic: Box<Diagnostic>,
    _marker: PhantomData<ErrorGuaranteed>,
}

Fields

state: DiagnosticBuilderState<'a>

diagnostic: Box<Diagnostic>

Diagnostic is a large type, and DiagnosticBuilder is often used as a return value, especially within the frequently-used PResult type. In theory, return value optimization (RVO) should avoid unnecessary copying. In practice, it does not (at the time of writing).

_marker: PhantomData<ErrorGuaranteed>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
