How to get the length of a `CStr`?

[wucke13]

I would love to see some .len() functions in all the type of this crate.

You can use .to_bytes().len().

Agreeing with @Amanieu. "length" has two distinct meanings here (length with and length without the nul), so it's better to explicitly indicate which length to get either by using .to_bytes() or .to_bytes_with_nul() when asking length.
