    source_map: Option<Lrc<SourceMapperDyn>>,
    short_message: 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.

    &mut self,
    db: &'a DiagnosticBuilder
) -> (MultiSpan, &'a [CodeSuggestion])

Formats the substitutions of the primary_span
