Function std.experimental.allocator.sharedAllocatorObject

Returns a dynamically-typed CSharedAllocator built around a given statically- typed allocator a of type A. Passing a pointer to the allocator creates a dynamic allocator around the allocator pointed to by the pointer, without attempting to copy or move it. Passing the allocator by value or reference behaves as follows.

RCISharedAllocator sharedAllocatorObject(A)(
  auto ref A a
) nothrow
if (!isPointer!A);

RCISharedAllocator sharedAllocatorObject(A)(
  A* pa
);

  • If A has no state, the resulting object is allocated in static shared storage.
  • If A has state and is copyable, the result will move the supplied allocator A a within. The result itself is allocated in its own statically-typed allocator.
  • If A has state and is not copyable, the result will move the passed-in argument into the result. The result itself is allocated in its own statically-typed allocator.
