[−][src]Crate qbsdiff
Fast and memory saving bsdiff 4.x compatible delta compressor and patcher.
Add dependency to Cargo.toml
under your project:
[dependencies]
qbsdiff = "1.1"
Build commands
The commands qbsdiff
and qbspatch
could be compiled with:
$ cargo build --release --bins --features cmd
$ target/release/qbsdiff -h
$ target/release/qbspatch -h
Examples
Apply patch to source and produce the target data:
use std::io; use qbsdiff::Bspatch; fn bspatch(source: &[u8], patch: &[u8]) -> io::Result<Vec<u8>> { let patcher = Bspatch::new(patch)?; let mut target = Vec::new(); // More complicated: Vec::with_capacity(patcher.hint_target_size() as usize); patcher.apply(source, io::Cursor::new(&mut target))?; Ok(target) }
Compare source with target then generate patch:
use std::io; use qbsdiff::Bsdiff; fn bsdiff(source: &[u8], target: &[u8]) -> io::Result<Vec<u8>> { let mut patch = Vec::new(); Bsdiff::new(source, target) .compare(io::Cursor::new(&mut patch))?; Ok(patch) }
Note that qbsdiff
would not generate exactly the same patch file as bsdiff
.
Only the patch file format is promised to be compatible.
