::byte-strings

Rust zero-cost byte strings manipulation, for a better and safer FFI

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::{cchar, cint}, };

/// 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!")); } ```
