type SafeRand ¶

type SafeRand struct {
	// contains filtered or unexported fields
}

SafeRand is a concurrency-safe source of pseudo-random numbers. The Go stdlib's math/rand.Source is not concurrency-safe. The global source in math/rand would be concurrency safe (due to its internal use of lockedSource), but it is prone to inter-package interference with the PRNG state.
