tempalloc's Issues
disabled opAssign prevents some valid usage
A short example, this fails:
import std.regionallocator;
void main()
{
RegionAllocator alloc; //will initialize later?
auto stack = RegionAllocatorStack(1<<22, GCScan.no);
alloc = stack.newRegionAllocator(); //calls disabled opAssign and fails
}
While it may seem backwards in this case, it's perfectly normal in case I have a struct A, and, for instance, want it to hold aloocator for it's private stack.
e.g. something like this:
struct A
{
RegionAllocator alloc;
this(uint page)
{
auto stack = stack = RegionAllocatorStack(1<<22, GCScan.no);
alloc = stack.newRegionAllocator();
}
//...
}
Workaround for now is to just comment out this opAssign (there is postblit, why disable opAssign?)
Postblit ctor range violation if no memory was allocated.
When compiling this:
import std.regionallocator;
void main() {
auto alloc = newRegionAllocator();
// auto mem = alloc.allocate(42); // uncomment this and it works
auto alloc2 = alloc;
}
I get:
