/*! Fast and memory saving bsdiff 4.x compatible delta compressor and patcher. Add dependency to `Cargo.toml` under your project: ```toml [dependencies] qbsdiff = "1.2" ``` Build commands -------------- The commands `qbsdiff` and `qbspatch` could be compiled with: ```shell $ cargo build --release --bins --features cmd $ target/release/qbsdiff -h $ target/release/qbspatch -h ``` Examples -------- Apply patch to source and produce the target data: ```rust 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: ```rust 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. */ #![forbid(unsafe_code)] pub mod bsdiff; pub mod bspatch; mod utils; pub use bsdiff::{Bsdiff, Compression}; pub use bspatch::Bspatch;
