Struct LruCacheOptions

pub struct LruCacheOptions { /* private fields */ }

Implementations

impl LruCacheOptions

pub fn set_capacity(&mut self, cap: usize)

Capacity of the cache, in the same units as the charge of each entry. This is typically measured in bytes, but can be a different unit if using kDontChargeCacheMetadata.

pub fn set_num_shard_bits(&mut self, val: c_int)

Cache is sharded into 2^num_shard_bits shards, by hash of key. If < 0, a good default is chosen based on the capacity and the implementation. (Mutex-based implementations are much more reliant on many shards for parallel scalability.)
