ups

Rust implementation of a UPS Patcher

Usage

Apply UPS patch:

use ups::UpsPatch;
use std::fs::File;
use std::io::{Read, Write};

//Load the contents of the source and patch files
let mut  source_file_content: Vec<u8> = vec![];
let mut  patch_file_content: Vec<u8> = vec![];
let mut  source_file = File::open("path/to/source/file")?;
source_file.read_to_end(&mut source_file_content);
let mut patch_file = File::open("path/to/patch/file")?;
patch_file.read_to_end(&mut patch_file_content);

//Apply the patch
let patch = UpsPatch::load(&patch_file_content)?;
let patched_file_content = patch.apply(&source_file_content)?;
//Write the target to a file
let mut target_file = File::open("path/to/target/file")?;
target_file.write_all(&*patched_file_content);

Create UPS Patch

use ups::UpsPatch;
use std::fs::File;
use std::io::{Read, Write};
//Load the contents of the source and patch files
let mut  source_file_content: Vec<u8> = vec![];
let mut  target_file_content: Vec<u8> = vec![];
let mut  source_file = File::open("path/to/source/file")?;
source_file.read_to_end(&mut source_file_content);
let mut target_file = File::open("path/to/patch/file")?;
target_file.read_to_end(&mut target_file_content);

//Create the UpsPatch
let patch = UpsPatch::create(&source_file_content, &target_file_content);
//Write the patch to a file
let patch_file_content = patch.get_patch_file_contents();
let mut patch_file = File::open("path/to/target/file")?;
patch_file.write_all(&patch_file_content);
