Encode a String to include c type escape and quotes

Hi I am trying to port a project haystack library to rust and one part of it is to output a string to zinc format (a souped up CSV)

I have wrapped a string to HString and to implement to_zinc that string has to be output with c like escaping and double quotes.

The spec shows examples like

Str: "hello" "foo\nbar\" (uses all standard escape chars as C like languages)

The file I am porting

I can port the java version easily but was wondering if there was a built in method that does this or crate. I can't seem to find one but it seems like a common thing.


Standard library has some escaping functions:


and I've found some crates:
