Re: randomSample

Meta:

You need to use the function array from std.array.

import std.array;

int[] source = [ ... ];
int[] sample = randomSample(source, 3).array();

In some cases it's also useful to use std.algorithm.copy:


void main() {
    import std.stdio, std.algorithm, std.random, std.array,
           std.range;

    immutable int[9] source = iota(10, 100, 10).array;
    source.writeln;
    int[3] sample;
    source[].randomSample(sample.length).copy(sample[]);
    sample.writeln;
}
