Struct freqfs::Cache

source · 
pub struct Cache<FE> { /* private fields */ }
Expand description

An in-memory cache layer over tokio::fs with least-frequently-used (LFU) eviction.

Implementations§

Initialize the cache.

cleanup_interval specifies how often cache cleanup should run in the background. max_file_handles specifies how many files are allowed to be evicted at once. If not specified, max_file_handles will default to 512.

This function should only be called once.

Panics: if max_file_handles is Some(0)

Load a filesystem directory into the cache.

After loading, all interactions with files under this directory should go through a DirLock or FileLock.
