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

ยงExample

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

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

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