Types

type AtomicSource

type AtomicSource uint64

An AtomicSource is a concurrency-safe SplitMix64 random number generator.

All methods on an AtomicSource may safely be called concurrently by multiple goroutines.

func (*AtomicSource) Int63

func (s *AtomicSource) Int63() int64

Int63 returns a 63-bit random number.

func (*AtomicSource) Seed

func (s *AtomicSource) Seed(seed int64)

Seed seeds the generator.

func (*AtomicSource) Uint64

func (s *AtomicSource) Uint64() uint64

Uint64Atomic returns a 64-bit random number. It may be safely called by multiple goroutines concurrently.

type Source

type Source uint64

A Source is a SplitMix64 random number generator.

func (*Source) Int63

func (s *Source) Int63() int64

Int63 returns a non-negative pseudo-random 63-bit integer as an int64.

func (*Source) Seed

func (s *Source) Seed(seed int64)

Seed uses the provided seed value to initialize the generator to a deterministic state.

func (*Source) Uint64

func (s *Source) Uint64() uint64

Uint64 returns a pseudo-random 64-bit value as a uint64.
