Hello,
You can try the following:
struct Node
{
char[64] arr;
}
enum numNodes = 100_000_000;
void[] buf = GCAllocator.instance.allocate(numNodes *
Node.sizeof);
auto reg = Region!(NullAllocator, 16)(cast(ubyte[])buf);
Thanks!
Is a `minAlign` of 16 recommended over 8 when allocating
classes or arrays?
Hi,
I'm glad it was helpful.
To be honest, I don't know which alignment would be better and
it probably depends on your machine.
This here says that 16 would work just fine [1] so I would go
with that.

Thanks. I presume if we know what type we should allocate, in my
case a class `C`, we should use `C.alignof` otherwise we should
default to `platformAlignment`.
