source§fn emit_diagnostic(&mut self, diag: &Diagnostic)
fn emit_diagnostic(&mut self, diag: &Diagnostic)
Emit a structured diagnostic.
source§fn should_show_explain(&self) -> bool
fn should_show_explain(&self) -> bool
Checks if should show explanations about “rustc –explain”
source§fn supports_color(&self) -> bool
fn supports_color(&self) -> bool

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

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(
