Syntax
template<typename InElementType, EQueueMode Mode>
class TQueueG
Remarks
Simple templated queue following Unreal's TQueue_ implementation using a lock-free linked list. We're doing this instead of using a simple array/etc. since it matches Unreal's implementation 1:1 apart from usage of the standard library for atomics. TODO: (yiliang.siew) Allow for custom allocators as the rest of uLang_ does. TODO: (yiliang.siew) See if some of the memory ordering requirements can be relaxed. For now since it guarantees an MFENCE_ instruction on x86-64 arch. Unreal issues a mm_sfence intrinsic, which I'm not sure if I can guarantee via `std::atomic_.
