Enum rustc_errors::diagnostic_builder::DiagnosticBuilderState

enum DiagnosticBuilderState<'a> {
    Emittable(&'a Handler),
    AlreadyEmittedOrDuringCancellation,
}

Variants

Emittable(&'a Handler)

Initial state of a DiagnosticBuilder, before .emit() or .cancel().

The Diagnostic will be emitted through this Handler.

AlreadyEmittedOrDuringCancellation

State of a DiagnosticBuilder, after .emit() or during .cancel().

The Diagnostic will be ignored when calling .emit(), and it can be assumed that .emit() was previously called, to end up in this state.

While this is also used by .cancel(), this state is only observed by the Drop impl of DiagnosticBuilderInner, as .cancel() takes self by-value specifically to prevent any attempts to .emit().

Trait Implementations

impl<'a> Clone for DiagnosticBuilderState<'a>

fn clone(&self) -> DiagnosticBuilderState<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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.
