Function rocket::mtls::oid::asn1_rs::nom::bytes::streaming::escaped

pub fn escaped<Input, Error, F, G, O1, O2>(
    normal: F,
    control_char: char,
    escapable: G,
) -> impl FnMut(Input)
where
    Input: Clone + Offset + InputLength + InputTake + InputTakeAtPosition + Slice<RangeFrom<usize>> + InputIter,
    <Input as InputIter>::Item: AsChar,
    F: Parser<Input, O1, Error>,
    G: Parser<Input, O2, Error>,
    Error: ParseError<Input>,

Available on crate feature mtls only.

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::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")));
