escaped!(&[T] -> IResult<&[T], &[T]>, T, &[T] -> IResult<&[T], &[T]>) => &[T] -> IResult<&[T], &[T]> 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
