Types

type Source

type Source interface {
	// Uint64 returns a random number in [0, MaxUint64] and advances the
	// generator's state.
	Uint64() uint64
}

type Uniform

type Uniform interface {
	Initialize(sampleRange uint64)
	// Sample returns length numbers in the range [0,sampleRange). If there
	// aren't enough numbers in the range, false is returned. If length is
	// negative the implementation may panic.
	Sample(length int) ([]uint64, bool)

	Next() (uint64, bool)
	Reset()
}

Uniform samples values without replacement in the provided range
