Expand description
Bloom filter configuration parameters.
Fields
elements: usize
records count in one blob.
hashers_count: usize
number of hash functions, the more hash functions. you have, the slower bloom filter, and the quicker it fills up. If you have too few, however, you may suffer too many false positives.
max_buf_bits_count: usize
number of bits in the inner buffer.
buf_increase_step: usize
filter buf increase value.
preferred_false_positive_rate: f64
filter incrementally increases buffer size by step and checks result false positive rate to be less than param. It stops once buffer reaches size of max_buf_bits_count.
