Trait Implementations

impl Emitter for SilentEmitter

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

fn emit_diagnostic(&mut self, _: &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. This is currently only supported for the JSON format, other formats can, and will, simply ignore it.

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

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

Emit list of unused externs

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
) -> (MultiSpan, &'a [CodeSuggestion])

Formats the substitutions of the primary_span
