Enum TargetHllType 

pub enum TargetHllType {
    Hll4,
    Hll6,
    Hll8,
}

Controls the internal representation HLL uses to store per-bucket state, trading memory for accuracy. Mirrors upstream’s datasketches::target_hll_type.

Hll4 is the most memory-compact; Hll8 is the least compact but fastest to update and most accurate at small cardinalities.

Variants

Hll4

4 bits per bucket — most memory-compact.

Hll6

6 bits per bucket.

Hll8

8 bits per bucket — least compact, fastest, most accurate at small n.
