pub fn new() -> LRUCacheOptions[src]
pub fn set_capacity(&mut self, capacity: usize)[src]
pub fn set_num_shard_bits(&mut self, num_shard_bits: i32)[src]
the recommanded shard_bits is 6, also you can set a larger value as long as it is smaller than 20, also you can set shard_bits to -1, RocksDB will choose a value for you the recommanded capacity_limit is 0(false) if your memory is sufficient the recommanded pri_ratio should be 0.05 or 0.1
