Nicholas Nethercote aa6bfaf04b Make rustc_lexer::cursor::Cursor public. ... `Cursor` is currently hidden, and the main tokenization path uses `rustc_lexer::first_token` which involves constructing a new `Cursor` for every single token, which is weird. Also, `first_token` also can't handle empty input, so callers have to check for that first. This commit makes `Cursor` public, so `StringReader` can contain a `Cursor`, which results in a simpler structure. The commit also changes `StringReader::advance_token` so it returns an `Option<Token>`, simplifying the the empty input case.		2022-09-26 13:36:35 +10:00
