Parser for the IPS patch format.
Handles run-length encoded hunks as well as the truncation extension.
Example
Patching a ROM from an IPS file:
use std::fs::{self, File};
use std::io::{Seek, SeekFrom, Write};
use ips::Patch;
let mut rom = File::open("Super Metroid.sfc")?;
let patch_contents = fs::read("Hyper Metroid.ips")?;
let patch = Patch::parse(&patch_contents)?;
for hunk in patch.hunks() {
rom.seek(SeekFrom::Start(hunk.offset() as u64))?;
rom.write_all(hunk.payload())?;
}
if let Some(truncation) = patch.truncation() {
rom.set_len(truncation as u64)?;
}
