Functions

• kleene_op 🔒
  Takes a token and returns Some(KleeneOp) if the token is + * or ?. Otherwise, return None.
• maybe_emit_macro_metavar_expr_concat_feature 🔒
• maybe_emit_macro_metavar_expr_feature 🔒
  Asks for the macro_metavar_expr feature if it is not enabled
• 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.
• span_dollar_dollar_or_metavar_in_the_lhs_err 🔒
