nom crate different input types

[brave tusk]

I have a parser function in nom, which takes &[u8] as input. Now I want to use it from a function which uses &str. I want to convert between the result types IResult<&[u8], _> and IResult<&str, _> with into(), but (obviously) that doesn't work. Is there another way?

normally you shouldn't mix parsing of &str and &[u8], you can usually do everything on &[u8]

converting IResult<&str, _> should be easy: res.map(|s| s.as_bytes());
the other way without checks isn't allowed, because &str has to be utf-8, you can use the std::str::from_utf8 function for the conversion
