Enum FilterParams 

pub enum FilterParams {
    FalsePositiveRate(f64),
    HashCount(u32),
}

Configuration parameter for creating a Bloom Filter.

Specify either the desired false positive rate (f64) or the specific number of hash functions (u32) to use.

Variants

FalsePositiveRate(f64)

Target false positive rate (between 0.0 and 1.0). The filter will calculate optimal bits (m) and hashes (k).

HashCount(u32)

Target number of hash functions (k). The filter will calculate the optimal bits (m) to satisfy the 50% fill rate assumption for this k (p = 2^-k).
