<sup>1</sup> You must ensure raw data comes with a valid representation for the string type (e.g., UTF-8 data for a `String`).


<sup>2</sup> Only on some platforms `std::os::<your_os>::ffi::OsStrExt` exists with helper methods to get a raw `&[u8]` representation of the underlying `OsStr`. Use the rest of the table to go from there, e.g.:

```
use std::os::unix::ffi::OsStrExt;
let bytes: &[u8] = my_os_str.as_bytes();
CString::new(bytes)?
```
<sup>2</sup> This operation is **unsafe** and you need to additional legality checks based on your platform.

<sup>3</sup> The `c_char` **must** have come from a previous `CString`. If it comes from FFI see `&CStr` instead.
