Struct ph::FPHash2Conf

pub struct FPHash2Conf<GS: GroupSize = TwoToPowerBits, SS: SeedSize = TwoToPowerBitsStatic<2>, S = BuildDefaultSeededHasher> { /* private fields */ }

Configuration that is accepted by FPHash2 constructors.

Implementations

impl<SS: SeedSize> FPHash2Conf<TwoToPowerBits, SS>

pub fn bps(bits_per_seed: SS) -> Self

Returns configuration that uses seeds of size given in bits.

impl<GS: GroupSize> FPHash2Conf<GS>

pub fn bpg(bits_per_group: GS) -> Self

Returns configuration that uses groups of size given in bits.

impl<GS: GroupSize, SS: SeedSize> FPHash2Conf<GS, SS>

pub fn bps_bpg(bits_per_seed: SS, bits_per_group: GS) -> Self

Returns configuration that uses seeds and groups of sizes given in bits.
