Functions

kleene_op

Takes a token and returns Some(KleeneOp) if the token is + * or ?. Otherwise, return None.

parse

Takes a tokenstream::TokenStream and returns a Vec<self::TokenTree>. Specifically, this takes a generic TokenStream, such as is used in the rest of the compiler, and returns a collection of TokenTree for use in parsing a macro.

parse_kleene_op

Parse the next token tree of the input looking for a KleeneOp. Returns

parse_sep_and_kleene_op

Attempt to parse a single Kleene star, possibly with a separator.

parse_tree

Takes a tokenstream::TokenTree and returns a self::TokenTree. Specifically, this takes a generic TokenTree, such as is used in the rest of the compiler, and returns a TokenTree for use in parsing a macro.
