Required Methods§

Source

fn pattern(&self, context: &ParsingContext) -> JsRegex

pattern(context). Return a clone of a cached regex; cloning is cheap.

Source

fn extract(&self, context: &ParsingContext, m: &mut RegexMatch) -> Extracted

extract(context, match). m.index is the byte offset of the match in context.text. Like upstream, an extractor may move m.index before returning Extracted::None to control where the search resumes.
