escaped!(T -> IResult<T, T>, U, T -> IResult<T, T>) => T -> IResult<T, T> where T: InputIter, U: AsChar 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

Example

 named!(esc, escaped!(call!(digit1), '\\', one_of!("\"n\\")));
 assert_eq!(esc(&b"123;"[..]), Ok((&b";"[..], &b"123"[..])));
 assert_eq!(esc(&b"12\\\"34;"[..]), Ok((&b";"[..], &b"12\\\"34"[..])));
