Module diff 

Two-level Merkle diff for incremental change detection.

Level 1: Compare directory mtimes — skip entire subtrees if unchanged. Level 2: For changed directories, stat files and blake3-hash dirty ones.

Structs

DiffResult

Result of diffing the filesystem against a manifest.

Functions

compute_diff

Compare the filesystem at root against the manifest to find changes.

compute_diff_with_options

Compare the filesystem at root against the manifest with explicit walk filters. Excluded files are treated like deleted manifest entries so stale cached chunks are pruned from the index.

hash_file

Compute the blake3 hash of a file’s content.

mtime_secs

Get the mtime of a path in seconds since epoch.
