Trait hyperloglog_rs::iter::EstimateIterCardinality

pub trait EstimateIterCardinality {
    // Required method
    fn estimate_cardinality<const PRECISION: usize, const BITS: usize>(
        self
    ) -> f32;
}

A trait for estimating the cardinality of an iterator.

Required Methods

fn estimate_cardinality<const PRECISION: usize, const BITS: usize>(self) -> f32

Estimate the cardinality of the iterator.

Arguments

• self - An iterator over elements to estimate the cardinality of.

Type parameters

• PRECISION - The precision to use for the HyperLogLog counter.
• BITS - The number of bits per register in the HyperLogLog counter.
