Module plugin_cache 

Plugin source cache — stores side effects of source/. in SQLite.

First source: execute normally, capture state delta, write cache on worker thread. Subsequent sources: check mtime, replay cached side effects in microseconds.

Cache key: (canonical_path, mtime_secs, mtime_nsecs) Cache invalidation: mtime mismatch → re-source, update cache.

Structs

PluginCache

SQLite-backed plugin cache.

PluginDelta

Side effects captured from sourcing a plugin file.

Enums

AliasKind

Constants

BYTECODE_VERSION

On-disk format version for cached fusevm chunks. Bumped when fusevm’s bincode layout changes in a non-backward-compat way. Cached blobs are stored as [VERSION_BYTE, bincode_bytes...]; readers verify the prefix and treat any mismatch as a cache miss (the source file is recompiled).

Functions

default_cache_path

Default path for the plugin cache db.

file_mtime

Get mtime from file metadata as (secs, nsecs).
