Struct HyperLogLog 

pub struct HyperLogLog { /* private fields */ }

HyperLogLog with configurable precision (b bits for register count).

Implementations

pub fn add(&mut self, data: &[u8])

pub fn count(&self) -> u64

Estimate the number of distinct elements.

pub fn merge(&mut self, other: &HyperLogLog)

pub fn reset(&mut self)

pub fn precision(&self) -> usize

pub fn num_registers(&self) -> usize
