Trait Implementations

impl Emitter for HumanEmitter

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

fn emit_diagnostic(&mut self, diag: DiagInner)

Emit a structured diagnostic.

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 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<DiagInner>)

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 primary_span_formatted( &mut self, primary_span: &mut MultiSpan, suggestions: &mut Vec<CodeSuggestion>, fluent_args: &FluentArgs<'_>, )

Formats the substitutions of the primary_span

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

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

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

impl Translate for HumanEmitter

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: &[(DiagMessage, Style)], args: &FluentArgs<'_>, ) -> Cow<'_, str>

Convert DiagMessages to a string, performing translation if necessary.

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

Convert a DiagMessage 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.
