Struct rustc_errors::emitter::SilentEmitter

pub struct SilentEmitter {
    pub fatal_handler: Handler,
    pub fatal_note: Option<String>,
}

An emitter that does nothing when emitting a non-fatal diagnostic. Fatal diagnostics are forwarded to fatal_handler to avoid silent failures of rustc, as witnessed e.g. in issue #89358.

Fields

fatal_handler: Handler

fatal_note: Option<String>

Trait Implementations

impl Emitter for SilentEmitter

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

fn emit_diagnostic(&mut self, d: &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<Diagnostic>)

fn emit_unused_externs(&mut self, _lint_level: Level, _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,
    fluent_args: &FluentArgs<'_>
) -> (MultiSpan, &'a [CodeSuggestion])

Formats the substitutions of the primary_span

fn fix_multispans_in_extern_macros_and_render_macro_backtrace(
    &self,
    source_map: &Option<Lrc<SourceMap>>,
    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,
    source_map: &Option<Lrc<SourceMap>>,
    span: &mut MultiSpan,
    children: &mut Vec<SubDiagnostic>
)

fn fix_multispan_in_extern_macros(
    &self,
    source_map: &Lrc<SourceMap>,
    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 to_fluent_args<'arg>(&self, args: &[DiagnosticArg<'arg>]) -> FluentArgs<'arg>

Convert diagnostic arguments (a rustc internal type that exists to implement Encodable/Decodable) into FluentArgs which is necessary to perform translation.

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<'_>
) -> Cow<'_, str>

Convert a DiagnosticMessage 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.
