Detailed Description

Describes a request to create or resolve a GPU resource during render pipeline compilation.

This structure encapsulates both the intended resource type and its creation parameters, and is typically used by resource provider interfaces or pass hooks (e.g. QueryResourceProvider).

Only one variant inside the union is valid at a time, as determined by m_Type.

Example usage:

• A pass emitting a Texture pin may populate m_Texture with desired resolution, format, and usage.
• The graph compiler or engine module inspects the request and returns an appropriate runtime handle.
