Expand description

Central store of data.

Fields§

§pages: FxHashMap<u64, Arc<Mutex<PageInfo>>>

Page number -> page info.

§total: i64

Total size of current pages.

§mem_limit: usize

trim_cache reduces total to mem_limit (or below).

§read: u64

Total number of page accesses.

§miss: u64

Total number of misses ( data was not already loaded ).
