Unescape (zero copy)

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

It supports custom escape sequence parsers intead of the standard C-style escape sequences as well; an example of this can be found in tests/lua_escapes.rs, using the library to parse Lua escape sequences.

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

Usage

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