Implementations§

Source§

impl AnnotateSnippetEmitter

Source

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

Source

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.
