Function winnow::bytes::streaming::escaped_transform

pub fn escaped_transform<I, Error, F, G, Output>(
    normal: F,
    control_char: char,
    transform: G
) -> impl FnMut(I) -> IResult<I, Output, Error>where
    I: Stream + Offset,
    <I as Stream>::Token: AsChar,
    Output: Accumulate<<I as Stream>::Slice>,
    F: Parser<I, <I as Stream>::Slice, Error>,
    G: Parser<I, <I as Stream>::Slice, Error>,
    Error: ParseError<I>,

👎Deprecated since 0.1.0: Replaced with <code>winnow::character::escaped_transform</code> with input wrapped in <code>winnow::Partial</code>

Matches a byte string with escaped characters.

• The first argument matches the normal characters (it must not match the control character)
• The second argument is the control character (like \ in most languages)
• The third argument matches the escaped characters and transforms them

As an example, the chain abc\tdef could be abc def (it also consumes the control character)

use winnow::bytes::streaming::{escaped_transform, tag};
use winnow::character::streaming::alpha1;
use winnow::branch::alt;
use winnow::combinator::value;

fn parser(input: &str) -> IResult<&str, String> {
  escaped_transform(
    alpha1,
    '\\',
    alt((
      value("\\", tag("\\")),
      value("\"", tag("\"")),
      value("\n", tag("n")),
    ))
  )(input)
}

assert_eq!(parser("ab\\\"cd\""), Ok(("\"", String::from("ab\"cd"))));

WARNING: Deprecated, replaced with winnow::character::escaped_transform with input wrapped in winnow::Partial
