HyperLogLogResult

@Serializable
@SerialName(value = "HyperLogLogResult")
data class HyperLogLogResult(val estimate: Double, val precision: Int, val registers: IntArray, val totalSeen: Long) : HasObservationCount(source)

HyperLogLog snapshot. estimate is the corrected cardinality (linear counting at the small-range, raw HLL elsewhere). registers are the dense rho values per bucket and are required to merge two snapshots without loss; precision selects bucket count m = 2^precision. totalSeen is the unweighted update count.

open val isEmpty: Boolean

True when no observation has been folded in, so every other field is a placeholder.
