uniform

hap random distribution

Returns a uniformly selected member of enum E. If no random number generator is passed, uses the default rndGen.

  1. auto uniform(T1 a, T2 b)
  2. auto uniform(T1 a, T2 b, UniformRNG rng)
  3. auto uniform(T1 a, T2 b, UniformRNG rng)
  4. auto uniform(UniformRNG rng)
  5. auto uniform()
  6. auto uniform(UniformRNG rng)
    auto
    uniform
    (
    E
    UniformRNG
    )
    (
    UniformRNG rng
    )
    if (
    is(E == enum) &&
    isUniformRNG!UniformRNG
    )
  7. auto uniform()

Examples

enum Fruit { Apple = 12, Mango = 29, Pear = 72 }
foreach (immutable _; 0 .. 100)
{
    foreach (immutable f; [uniform!Fruit(), rndGen.uniform!Fruit()])
    {
        assert(f == Fruit.Apple || f == Fruit.Mango || f == Fruit.Pear);
    }
}
