Expand description

Matches a byte string with escaped characters.

  • The first argument matches the normal characters (it must not accept the control character)
  • The second argument is the control character (like \ in most languages)
  • The third argument matches the escaped characters


use nom::bytes::complete::escaped;
use nom::character::complete::one_of;

fn esc(s: &str) -> IResult<&str, &str> {
  escaped(digit1, '\\', one_of(r#""n\"#))(s)

assert_eq!(esc("123;"), Ok((";", "123")));
assert_eq!(esc(r#"12\"34;"#), Ok((";", r#"12\"34"#)));
