ResourceState

Remarks

Specified against Vulkan's synchronization2 rather than the older source-and-destination-stage model, and deliberately: D3D12's Enhanced Barriers map onto it directly, so a D3D12 backend added later is additive rather than a re-specification (ADR-001). The GL backend elides barriers entirely, which is legal because GL's model is implicit.

Flags rather than a single state, because a resource can legitimately be several things at once — sampled by the fragment stage while also being a copy source — and a barrier has to name all of them or the driver serialises more than it needs to.
