libxdiff

Safe, idiomatic Rust bindings for the libxdiff C library.

Usage

Add this to your Cargo.toml:

[dependencies]
libxdiff = "0.2"

Example

use core::str::from_utf8;
use libxdiff::MMFile;

let mut f1 = MMFile::from_bytes(b"hello world\n");
let mut f2 = MMFile::from_bytes(b"hello world!\n");
let mut diff_lines = Vec::<String>::new();
f1.diff_raw(&mut f2, |line: &[u8]| {
    diff_lines.push(from_utf8(line).unwrap().to_owned());
})
.unwrap();
assert_eq!(
    diff_lines,
    vec![
        "@@ -1,1 +1,1 @@\n",
        "-", "hello world\n",
        "+", "hello world!\n",
    ],
);

Linkage

Upstream libxdiff is small and has no dependencies, so this crate links it statically.
