Expand description
Emitter trait for emitting errors.
Required Methods§
Sourcefn emit_diagnostic(&mut self, diag: DiagInner)
fn emit_diagnostic(&mut self, diag: DiagInner)
Emit a structured diagnostic.
fn source_map(&self) -> Option<&SourceMap>
Provided Methods§
Sourcefn emit_artifact_notification(&mut self, _path: &Path, _artifact_type: &str)
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.
Sourcefn emit_future_breakage_report(&mut self, _diags: Vec<DiagInner>)
fn emit_future_breakage_report(&mut self, _diags: Vec<DiagInner>)
Emit a report about future breakage. Currently only supported for the JSON format.
Sourcefn emit_unused_externs(&mut self, _lint_level: Level, _unused_externs: &[&str])
fn emit_unused_externs(&mut self, _lint_level: Level, _unused_externs: &[&str])
Emit list of unused externs. Currently only supported for the JSON format.
Sourcefn should_show_explain(&self) -> bool
fn should_show_explain(&self) -> bool
Checks if should show explanations about “rustc –explain”
Sourcefn supports_color(&self) -> bool
fn supports_color(&self) -> bool
Checks if we can use colors in the current output stream.
Sourcefn primary_span_formatted(
&mut self,
primary_span: &mut MultiSpan,
suggestions: &mut Vec<CodeSuggestion>,
fluent_args: &FluentArgs<'_>,
)
fn primary_span_formatted( &mut self, primary_span: &mut MultiSpan, suggestions: &mut Vec<CodeSuggestion>, fluent_args: &FluentArgs<'_>, )
Formats the substitutions of the primary_span
There are a lot of conditions to this method, but in short:
-
If the current
DiagInner
has only one visibleCodeSuggestion
, we format thehelp
suggestion depending on the content of the substitutions. In that case, we modify the span and clear the suggestions. -
If the current
DiagInner
has multiple suggestions, we leaveprimary_span
and the suggestions untouched.
