Function syntax::ext::tt::transcribe::new_tt_reader_with_doc_flag [−] [src]

pub fn new_tt_reader_with_doc_flag(sp_diag: &Handler, interp: Option<HashMap<Name, Rc<NamedMatch>>>, imported_from: Option<Ident>, src: Vec<TokenTree>, desugar_doc_comments: bool) -> TtReader

Unstable (rustc_private)

The extra desugar_doc_comments flag enables reading doc comments like any other attribute which consists of meta and surrounding #[ ] tokens.

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.
