Function syntex_syntax::ext::tt::transcribe::new_tt_reader [−] [src]

pub fn new_tt_reader(sp_diag: &Handler, interp: Option<HashMap<Ident, Rc<NamedMatch>>>, src: Vec<TokenTree>) -> TtReader

This can do Macro-By-Example transcription. On the other hand, if src contains no TokenTree::Sequences, MatchNts or SubstNts, interp can (and should) be None.
