std.bitmanip.BitArray.opSliceAssign - multiple declarations

Function BitArray.opSliceAssign

Sets all the values in the BitArray to the value specified by val.

void opSliceAssign (
  bool val
) pure nothrow @nogc;

Example

import std.algorithm.comparison : equal;

auto b = BitArray([1, 0, 1, 0, 1, 1]);

b[] = true;
// all bits are set
assert(b.bitsSet.equal([0, 1, 2, 3, 4, 5]));

b[] = false;
// none of the bits are set
assert(b.bitsSet.empty);

Function BitArray.opSliceAssign

Sets the bits of a slice of BitArray starting at index start and ends at index ($D end - 1) with the values specified by val.

void opSliceAssign (
  bool val,
  ulong start,
  ulong end
) pure nothrow @nogc;

Example

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

auto b = BitArray([1, 0, 0, 0, 1, 1, 0]);
b[1 .. 3] = true;
assert(b.bitsSet.equal([0, 1, 2, 4, 5]));

bool[72] bitArray;
auto b1 = BitArray(bitArray);
b1[63 .. 67] = true;
assert(b1.bitsSet.equal([63, 64, 65, 66]));
b1[63 .. 67] = false;
assert(b1.bitsSet.empty);
b1[0 .. 64] = true;
assert(b1.bitsSet.equal(iota(0, 64)));
b1[0 .. 64] = false;
assert(b1.bitsSet.empty);

bool[256] bitArray2;
auto b2 = BitArray(bitArray2);
b2[3 .. 245] = true;
assert(b2.bitsSet.equal(iota(3, 245)));
b2[3 .. 245] = false;
assert(b2.bitsSet.empty);
