Struct FatalOnlyEmitter

pub struct FatalOnlyEmitter {
    pub fatal_emitter: Box<dyn Emitter + DynSend>,
    pub fatal_note: Option<String>,
}

An emitter that does nothing when emitting a non-fatal diagnostic. Fatal diagnostics are forwarded to fatal_emitter to avoid silent failures of rustc, as witnessed e.g. in issue #89358.

Fields

fatal_emitter: Box<dyn Emitter + DynSend>

fatal_note: Option<String>

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.
