Trait Implementations

impl FilterBuilder for BloomFilterBuilder

fn add_key(&mut self, key: &[u8], table_id: u32)

add key which need to be filter for construct filter data.

fn approximate_len(&self) -> usize

approximate memory of filter builder

fn finish(&mut self, memory_limiter: Option<Arc<MemoryLimiter>>) -> Vec<u8>

Builds Bloom filter from key hashes

fn create(fpr: f64, capacity: usize) -> Self

fn approximate_building_memory(&self) -> usize

approximate memory when finish filter

fn switch_block(&mut self, _memory_limiter: Option<Arc<MemoryLimiter>>)

fn add_raw_data(&mut self, _raw: Vec<u8>)

Add raw data which build by keys directly. Please make sure that you have finished the last block by calling switch_block

fn support_blocked_raw_data(&self) -> bool
