Module merkle_index 

Per-target consolidated Merkle signature index for large files (>256MB). Stores large Merkle signatures that exceed the 64KB xattr limit in a consolidated per-target index file at <target>/.foxing_meta/merkle.db.

One file per target, keyed by relative path. Avoids per-file sidecar proliferation and inode waste for large files.

Structs

FlushGuard

RAII guard that calls flush_all() on drop for daemon shutdown safety.

Functions

batch_set

Insert into the in-memory index WITHOUT flushing to disk. Caller must call flush() or flush_all() explicitly to persist.

flush

Explicitly flush a single target’s index to disk (crash-safe).

flush_all

Flush ALL targets in the global index cache to disk.

flush_guard

Create a FlushGuard that flushes all indexes on drop.

get

Retrieve a Merkle signature from the per-target index.

invalidate_cache

Invalidate the in-memory cache for a target (e.g., on target reconnect).

remove

Remove a Merkle signature from the index (file deleted or moved).

set

Store a Merkle signature in the per-target index (auto-flushes to disk).
