scroll_derive

Macros 1.1 implementing #[derive(Pread, Pwrite)]

Add derive annotations to your POD seamlessly and easily:

extern crate scroll;
#[macro_use]
extern crate scroll_derive;

#[derive(Debug, PartialEq, Pread, Pwrite)]
struct Data {
  id: u32,
  timestamp: f64,
}

use scroll::{Pread, Pwrite, Buffer, LE};

fn main (){
    let bytes = Buffer::new([0xefu8, 0xbe, 0xad, 0xde, 0, 0, 0, 0, 0, 0, 224, 63]);
    let data: Data = bytes.pread(0, LE).unwrap();
    println!("data: {:?}", &data);
    assert_eq!(data.id, 0xdeadbeefu32);
    let mut bytes2 = Buffer::with(0, ::std::mem::size_of::<Data>());
    bytes2.pwrite(data, 0, LE).unwrap();
    let data: Data = bytes.pread(0, LE).unwrap();
    let data2: Data = bytes2.pread(0, LE).unwrap();
    assert_eq!(data, data2);
