Unescape (zero copy)

Unescapes strings with C-style escape sequences, written to minimize memory copying. Other crates (e.g. unescaper) like to allocate every for every string, but most strings don't need any unescaping and so can be returned as-is. This library does that.

Supports no_std by returning an iterator, or can return a Cow that allocates as needed with the std feature (enabled by default).

No automated tests yet cause I'm lazy, but it has been manually tested for many cases.

Usage

assert_eq!(unescape_zero_copy::unescape(r"Hello\x0aworld").unwrap(), "Hello\nworld");
