Description
Both the reference (http://doc.rust-lang.org/reference.html#lexical-structure) and the grammar reference (http://doc.rust-lang.org/grammar.html#lexical-structure) are very incomplete with regards to the lexing rules. For example:
- lifetimes token not documented
- attributes token not documented
- character/string literal token rules are incomplete, they do not seem to specify the
b
/br#
prefixes for character and string literals.
I'm writing a lexer for an IDE (to do syntax highlighting), and since I'm not yet familar with Rust itself, this makes my life a bit harder...
