Struct GenericTrackingCopyCache

pub struct GenericTrackingCopyCache<M: Copy + Debug> { /* private fields */ }

Keeps track of already accessed keys. We deliberately separate cached Reads from cached mutations because we want to invalidate Reads’ cache so it doesn’t grow too fast.

Implementations

impl<M: Meter<Key, StoredValue> + Copy + Default> GenericTrackingCopyCache<M>

pub fn new(max_cache_size: usize, meter: M) -> GenericTrackingCopyCache<M>

Creates instance of TrackingCopyCache with specified max_cache_size, above which least-recently-used elements of the cache are invalidated. Measurements of elements’ “size” is done with the usage of Meter instance.

pub fn new_default(max_cache_size: usize) -> GenericTrackingCopyCache<M>

Creates instance of TrackingCopyCache with specified max_cache_size, above which least-recently-used elements of the cache are invalidated. Measurements of elements’ “size” is done with the usage of default Meter instance.

pub fn insert_read(&mut self, key: Key, value: StoredValue)

Inserts key and value pair to Read cache.

pub fn insert_write(&mut self, key: Key, value: StoredValue)

Inserts key and value pair to Write/Add cache.

pub fn insert_prune(&mut self, key: Key)

Inserts key and value pair to Write/Add cache.

pub fn get(&mut self, key: &Key) -> Option<&StoredValue>

Gets value from key in the cache.

pub fn is_pruned(&self, key: &Key) -> bool

Does the prune cache contain key.
