* feat: u64 for --bytes and --ignore-initial fix: bumped up tempfile to "3.26.0" The variables for --bytes, --ignore-initial and line count where size 'usize', thus limiting the readable bytes on 32-bit systems. GNU cmp is compiled with LFS (Large File Support) and allows i64 values. This is now all u64, which works also on 32-bit systems with Rust. There is no reason to implement a 32-bit barrier for 32 bit machines. Additionally the --bytes limit can be set to 'u128' using the feature "cmp_bytes_limit_128_bit". The performance impact would be negligible, as there only few calculations each time a full block is read from the file. --------- Co-authored-by: Gunter Schmidt <gsgit@beadsoft.de> Co-authored-by: Sylvestre Ledru <sylvestre@debian.org>
The goal of this package is to be a drop-in replacement for the diffutils commands (diff, cmp, diff3, sdiff) in Rust.
Based on the incomplete diff generator in https://github.com/rust-lang/rust/blob/master/src/tools/compiletest/src/runtest.rs, and made to be compatible with GNU's diff and patch tools.
