## Example

Featuring the `c_str!` macro to create **valid C string literals** with
literally no runtime cost!

```rust
#[macro_use]
extern crate byte_strings;

/// Some lib
mod safe {
    use ::std::{
        ffi::CStr,
        os::raw::{c_char, c_int},
    };

    /// private unsafe C FFI
    mod ffi {
        use super::*;

        extern "C" {
            pub
            fn puts (_: *const c_char)
              -> c_int
            ;
        }
    }

    /// lib API: safe Rust wrapper => uses `CStr`
    pub
    fn puts (message: &'_ CStr)
      -> i32
    {
        unsafe {
            ffi::puts(message.as_ptr()) as i32
        }
    }
}

fn main ()
{
    safe::puts(c!("Hello, World!"));
}
```
