pub struct SilentEmitter {
    pub fatal_handler: Handler,
    pub fatal_note: Option<String>,
}
Expand description

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

Trait Implementations§

source§

impl Emitter for SilentEmitter

source§

fn source_map(&self) -> Option<&Lrc<SourceMap>>

source§

fn emit_diagnostic(&mut self, d: &Diagnostic)

Emit a structured diagnostic.
source§

fn emit_artifact_notification(&mut self, _path: &Path, _artifact_type: &str)

Emit a notification that an artifact has been output. This is currently only supported for the JSON format, other formats can, and will, simply ignore it.
source§

fn emit_future_breakage_report(&mut self, _diags: Vec<Diagnostic>)

source§

fn emit_unused_externs(&mut self, _lint_level: Level, _unused_externs: &[&str])

Emit list of unused externs
source§

fn should_show_explain(&self) -> bool

Checks if should show explanations about “rustc –explain”
source§

fn supports_color(&self) -> bool

Checks if we can use colors in the current output stream.

fn primary_span_formatted<'a>( &mut self, diag: &'a Diagnostic, fluent_args: &FluentArgs<'_> ) -> (MultiSpan, &'a [CodeSuggestion])

Formats the substitutions of the primary_span Read more

fn render_multispan_macro_backtrace( &self, span: &mut MultiSpan, always_backtrace: bool )

source§

fn fix_multispans_in_extern_macros( &self, span: &mut MultiSpan, children: &mut Vec<SubDiagnostic> )

source§

source§

impl Translate for SilentEmitter

source§

fn fluent_bundle(&self) -> Option<&Lrc<FluentBundle>>

Return FluentBundle with localized diagnostics for the locale requested by the user. If no language was requested by the user then this will be None and fallback_fluent_bundle should be used.
source§

fn fallback_fluent_bundle(&self) -> &FluentBundle

Return FluentBundle with localized diagnostics for the default locale of the compiler. Used when the user has not requested a specific language or when a localized diagnostic is unavailable for the requested locale.
source§

fn translate_messages( &self, messages: &[(DiagnosticMessage, Style)], args: &FluentArgs<'_> ) -> Cow<'_, str>

Convert DiagnosticMessages to a string, performing translation if necessary.
source§

fn translate_message<'a>( &'a self, message: &'a DiagnosticMessage, args: &'a FluentArgs<'_> ) -> Result<Cow<'_, str>, TranslateError<'_>>

Convert a DiagnosticMessage to a string, performing translation if necessary.

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.
