Functions

dlang_hll_count

ulong dlang_hll_count(HLL hll)

Returns estimated cardinality number.

dlang_hll_create

int dlang_hll_create(HLL hll, uint p, uint pPrime, HLL_Malloc malloc, HLL_Realloc realloc, HLL_Free free)

Computes 64bit Murmurhash3 value.

dlang_hll_put_hash

void dlang_hll_put_hash(HLL hll, ulong hash)

dlang_hll_put_uuid

void dlang_hll_put_uuid(HLL hll, UUID uuid)

dlang_hll_unite_temp

void dlang_hll_unite_temp(HLL hll)
