Filesystem-backed :class:Cache adapter (lite -- stdlib only).
snappy compression is delegated to the abstract base; it degrades
gracefully when python-snappy is not installed.
LocalFileCache(prefix, hash_keys=True, default_ttl=DEFAULT_TTL_SECONDS, root_path=None, max_size=DEFAULT_LOCAL_FILE_CACHE_MAX_SIZE, use_compression=True)
Bases: Cache
A local file cache for our shenanigans.
