Function std.bitmanip.bitsSet

Range that iterates the indices of the set bits in value. Index 0 corresponds to the least significant bit. For signed integers, the highest index corresponds to the sign bit.

auto bitsSet(T)(
  const T value
) pure nothrow @nogc
if (isIntegral!T);

Example

import std.algorithm.comparison : equal;
import std.range : iota;

assert(bitsSet(1).equal([0]));
assert(bitsSet(5).equal([0, 2]));
assert(bitsSet(-1).equal(iota(32)));
assert(bitsSet(int.min).equal([31]));
