Trait Implementations

impl Emitter for SilentEmitter

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

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

Emit a structured diagnostic.

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

Emit a notification that an artifact has been output. Currently only supported for the JSON format.

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

Emit a report about future breakage. Currently only supported for the JSON format.

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

Emit list of unused externs. Currently only supported for the JSON format.

fn should_show_explain(&self) -> bool

Checks if should show explanations about “rustc –explain”

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

fn fix_multispans_in_extern_macros_and_render_macro_backtrace( &self, span: &mut MultiSpan, children: &mut Vec<SubDiagnostic>, level: &Level, backtrace: bool )

fn render_multispans_macro_backtrace( &self, span: &mut MultiSpan, children: &mut Vec<SubDiagnostic>, backtrace: bool )

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

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

fn fix_multispan_in_extern_macros(&self, span: &mut MultiSpan)

impl Translate for SilentEmitter

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.

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.

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

Convert DiagnosticMessages to a string, performing translation if necessary.

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

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