解析和操作补丁文件

本crate提供对统一diff文件及其相关文件（例如quilt）的解析和编辑支持。

lib.rs:

用于解析和操作补丁的crate。

示例

use patchkit::parse::parse_patch;
use patchkit::patch::{Patch as _, UnifiedPatch, Hunk, HunkLine};

let patch = UnifiedPatch::parse_patch(vec![
    "--- a/file1\n",
    "+++ b/file1\n",
    "@@ -1,1 +1,1 @@\n",
    "-a\n",
    "+b\n",
].into_iter().map(|s| s.as_bytes())).unwrap();

assert_eq!(patch, UnifiedPatch {
    orig_name: b"a/file1".to_vec(),
    mod_name: b"b/file1".to_vec(),
    orig_ts: None,
    mod_ts: None,
    hunks: vec![
        Hunk {
            mod_pos: 1,
            mod_range: 1,
            orig_pos: 1,
            orig_range: 1,
            lines: vec![
                HunkLine::RemoveLine(b"a\n".to_vec()),
                HunkLine::InsertLine(b"b\n".to_vec()),
            ],
            tail: None
        },
    ],
});

let applied = patch.apply_exact(&b"a\n"[..]).unwrap();
assert_eq!(applied, b"b\n");
