func MutateByteSlice ¶
Contract: !bytes.Equal(input, output) && len(input) >= len(output)
Types ¶
type Rand ¶
Rand is a prng, that is seeded with OS randomness. The OS randomness is obtained from crypto/rand, however none of the provided methods are suitable for cryptographic usage. They all utilize math/rand's prng internally.
All of the methods here are suitable for concurrent use. This is achieved by using a mutex lock on all of the provided methods.
func (*Rand) Intn ¶
Intn returns, as an int, a uniform pseudo-random number in the range [0, n). It panics if n <= 0.
