DB cache manager
Implementations
impl<T> CacheManager<T> where
T: Eq + Hash, [src]
T: Eq + Hash,
pub fn new(
pref_cache_size: usize,
max_cache_size: usize,
bytes_per_cache_entry: usize
) -> Self[src]
pref_cache_size: usize,
max_cache_size: usize,
bytes_per_cache_entry: usize
) -> Self
Create new cache manager with preferred (heap) sizes.
pub fn note_used(&mut self, id: T)[src]
Mark element as used.
pub fn collect_garbage<F>(&mut self, current_size: usize, notify_unused: F) where
F: FnMut(HashSet<T>) -> usize, [src]
F: FnMut(HashSet<T>) -> usize,
Collects unused objects from cache. First params is the current size of the cache. Second one is an with objects to remove. It should also return new size of the cache.
