Function `escaped`

fn escaped<'a, I, Error, F, G>(normal: F, control_char: char, escapable: G) -> impl FnMut(I) -> crate::internal::IResult<I, I, Error>
where
    I: Clone + crate::traits::Offset + Input + 'a,
    <I as Input>::Item: crate::traits::AsChar,
    F: Parser<I, Error = Error>,
    G: Parser<I, Error = Error>,
    Error: ParseError<I>

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

# use nom::{Err, error::ErrorKind, Needed, IResult};
# use nom::character::complete::digit1;
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"#)));
