Struct D3D12Resource 

pub struct D3D12Resource { /* private fields */ }

ID3D12Resource* keyed-mutex / shared-handle resource (Texture2D dimension).

Implementations

impl D3D12Resource

pub unsafe fn try_from_raw( resource: *mut c_void, luid: Option<(i32, u32)>, row_pitch: u32, keep_alive: Option<KeepAlive>, ) -> Result<Self, InvalidHandleError>

Wrap a raw Texture2D-dimension ID3D12Resource*. Borrowing: the handle is stored non-owningly, this type has no Drop, and every obligation below extends to each Clone.

Safety

• resource must point to a live ID3D12Resource of D3D12_RESOURCE_DIMENSION_TEXTURE2D. It is stored verbatim and the importer calls COM methods through the vtable at that address. Null is rejected as InvalidHandleError::NullPointer and is not a caller obligation.
• Refcount: no AddRef is taken and there is no Drop that would Release. The caller’s reference must outlive this value and every Clone of it; pass a keep_alive anchor to discharge that, or carry it directly when None.
• Cross-thread: unlike D3D11 this needs no opt-in — D3D12 objects are free-threaded by specification, which is what makes the unsafe impl Send + Sync below sound. The caller is still responsible for the usual D3D12 rules the importer cannot see: the resource must be in a state compatible with what the importer will transition from, and must not be evicted.
• luid, when Some, must be the LUID of the adapter the resource lives on; importers use it to refuse cross-adapter opens.
• row_pitch must be the resource’s footprint row pitch in bytes, or 0 when unknown.
