Function Vector.heapSwap
Swaps the contents of this
and rhs
only if both are heap allocated.
bool heapSwap
(
scope ref typeof(this) rhs
) scope;
Return true
if swap successed or false
if not (this
or rhs
is non heap allocated).
Examples
auto a = Vector!(int, 3) .build(1, 2, 3);
auto b = Vector!(int, 3) .build(6, 7, 8);
assert(a .heapSwap(b) == false);
assert(a == [1, 2, 3]);
assert(b == [6, 7, 8]);
a ~= 4;
b ~= 9;
assert(a == [1, 2, 3, 4]);
assert(b == [6, 7, 8, 9]);
assert(a .heapSwap(b) == true);
assert(a == [6, 7, 8, 9]);
assert(b == [1, 2, 3, 4]);
