Descrizione
Hello.
It would be nice to have a warning when using str::as_ptr() in a ffi call instead of using CStr.
For instance, in the following code:
unsafe { printf("Hello".as_ptr() as *const _) };
should give a warning and propose something like:
let cstring = CString::new("Hello".as_bytes()).unwrap();
unsafe { printf(cstring.as_ptr()) };
Thanks to add this lint.
