Function lazy_transform_str::unescape_backslashed_verbatim

#[must_use = "pure function"]pub fn unescape_backslashed_verbatim(string: &str) -> Cow<'_, String, str>

Replaces \ followed by any Unicode char in string with that char, as lazily as possible.
If \\ is found, this sequence is consumed at once and a single \ remains in the output.

Example

use cervine::Cow;
use lazy_transform_str::unescape_backslashed_verbatim;

let input = r#"A \"quoted\" word\\!"#;

let output = unescape_backslashed_verbatim(input);

assert_eq!(output, Cow::Owned(r#"A "quoted" word\!"#.into()));

let output = unescape_backslashed_verbatim(&output);

assert_eq!(output, Cow::Owned(r#"A "quoted" word!"#.into()));
