Enums
| EscapeError | Errors that can occur during string unescaping. |
| Mode | What kind of literal do we parse. |
Functions
| byte_from_char | |
| is_ascii | |
| scan_escape | |
| unescape_byte | Takes a contents of a byte literal (without quotes), and returns an unescaped byte or an error. |
| unescape_byte_literal | Takes a contents of a byte, byte string or raw byte string (without quotes) and produces a sequence of bytes or errors. Values are returned through invoking of the provided callback. |
| unescape_char | Takes a contents of a char literal (without quotes), and returns an unescaped char or an error |
| unescape_char_or_byte | |
| unescape_literal | Takes a contents of a literal (without quotes) and produces a sequence of escaped characters or errors. Values are returned through invoking of the provided callback. |
| unescape_raw_str_or_byte_str | Takes a contents of a string literal (without quotes) and produces a sequence of characters or errors. NOTE: Raw strings do not perform any explicit character escaping, here we only translate CRLF to LF and produce errors on bare CR. |
| unescape_str_or_byte_str | Takes a contents of a string literal (without quotes) and produces a sequence of escaped characters or errors. |
