Types

type SafeSplitMix64

type SafeSplitMix64 struct {
	SplitMix64
	// contains filtered or unexported fields
}

SafeSplitMix64 represents the state of a SplitMix64 random number generator with a mutex to make it safe for concurrent use.

func NewSafe

func NewSafe() *SafeSplitMix64

NewSafe creates a new safe SplitMix64 instance seeded with the current time.

func (*SafeSplitMix64) Float32

func (x *SafeSplitMix64) Float32() float32

Float32 generates a random float32 in the range [0.0, 1.0), which is safe for concurrent use.

func (*SafeSplitMix64) Float64

func (x *SafeSplitMix64) Float64() float64

Float64 generates a random float64 in the range [0.0, 1.0), which is safe for concurrent use.

func (*SafeSplitMix64) Int

func (x *SafeSplitMix64) Int(n int) int

Int generates a random integer in the range [0, n), which is safe for concurrent use.

func (*SafeSplitMix64) Int32

func (x *SafeSplitMix64) Int32() int32

Int32 generates a random 32-bit signed integer, which is safe for concurrent use.

func (*SafeSplitMix64) Int64

func (x *SafeSplitMix64) Int64() int64

Int64 generates a random 64-bit signed integer, which is safe for concurrent use.

func (*SafeSplitMix64) Marshal

func (x *SafeSplitMix64) Marshal() ([]byte, error)

Marshal returns the binary encoding of the current state of the random number generator, which is safe for concurrent use.

func (*SafeSplitMix64) Reset

func (x *SafeSplitMix64) Reset()

Reset resets the state of the random number generator to the seed value, which is safe for concurrent use.

func (*SafeSplitMix64) Seed

func (x *SafeSplitMix64) Seed(seed uint64)

Seed initializes the state of the random number generator with the given seed value, which is safe for concurrent use.

func (*SafeSplitMix64) State

func (x *SafeSplitMix64) State() uint64

State returns the current state of the random number generator, which is safe for concurrent use.

func (*SafeSplitMix64) Uint32

func (x *SafeSplitMix64) Uint32() uint32

Uint32 generates a random 32-bit unsigned integer, which is safe for concurrent use.

func (*SafeSplitMix64) Uint64

func (x *SafeSplitMix64) Uint64() uint64

Uint64 generates a random 64-bit unsigned integer, which is safe for concurrent use.

func (*SafeSplitMix64) Unmarshal

func (x *SafeSplitMix64) Unmarshal(data []byte) error

Unmarshal sets the state of the random number generator to the state represented by the input data, which is safe for concurrent use.

type SplitMix64

type SplitMix64 struct {
	// contains filtered or unexported fields
