Struct rustc_errors::annotate_snippet_emitter_writer::AnnotateSnippetEmitterWriter

pub struct AnnotateSnippetEmitterWriter {
    source_map: Option<Lrc<SourceMap>>,
    short_message: bool,
    ui_testing: bool,
    macro_backtrace: bool,
}

Generates diagnostics using annotate-snippet

Fields

source_map: Option<Lrc<SourceMap>>

short_message: bool

If true, hides the longer explanation text

ui_testing: bool

If true, will normalize line numbers with LL to prevent noise in UI test diffs.

macro_backtrace: bool

Implementations

impl AnnotateSnippetEmitterWriter

pub fn new(
    source_map: Option<Lrc<SourceMap>>,
    short_message: bool,
    macro_backtrace: bool
) -> Self

pub fn ui_testing(self, ui_testing: bool) -> Self

Allows to modify Self to enable or disable the ui_testing flag.

If this is set to true, line numbers will be normalized as LL in the output.

Trait Implementations

impl Emitter for AnnotateSnippetEmitterWriter

fn emit_diagnostic(&mut self, diag: &Diagnostic)

The entry point for the diagnostics generation

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

fn should_show_explain(&self) -> bool

Checks if should show explanations about “rustc –explain”

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 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
