pub fn unified_hunks(old_bytes: &[u8], new_bytes: &[u8]) -> Option<Vec<u8>>Expand description
The hunk body of a unified diff between two blobs: the @@ … @@ headers
and their +/-/context lines, with no ---/+++ file headers, as raw
bytes (git diffs are byte-oriented and do not require UTF-8). Returns
None when either side is binary by git’s heuristic — a NUL byte in
the first 8000 bytes — so a caller emits a Binary files … line instead.
An empty result means the blobs are textually identical.
Splitting the hunk body out lets callers wrap it in a git-shaped
diff --git header (with /dev/null for adds/deletes) while keeping the
algorithm — Myers diff with git-style hunk compaction — in one place.
