A complete GoldSrc demo parser and writer library

Example

use dem::Aux;
use dem::{parse_netmsg, write_demo, write_netmsg};
use dem::hldemo::Demo;
use dem::hldemo::FrameData;
use std::{fs::File, io::Read};

// prologue
let mut bytes = Box::new(Vec::new());
let mut f = File::open("example.dem").unwrap();
f.read_to_end(&mut bytes).unwrap();

let mut demo = Demo::parse(&bytes).unwrap();

// do stuffs
let aux = Aux::new();

for entry in &mut demo.directory.entries {
    for frame in &mut entry.frames {
        if let FrameData::NetMsg((_, data)) = &mut frame.data {
            let (_, netmsg) = parse_netmsg(data.msg, &aux).unwrap();
            // do netmsg things
            let bytes = write_netmsg(netmsg, &aux);
            data.msg = bytes.leak(); // hldemo does not own any data. Remember to free.
        }
    }
}

// write demo
write_demo("my_new_demo", demo).unwrap();
