| output | Reference to the NativeArray to write the data into. The NativeArray or underlying memory cannot be Disposed until the request is complete. | 
| src | The Texture resource to read the data from. | 
| mipIndex | The index of the mipmap to fetch. | 
| dstFormat | The target TextureFormat of the data. Conversion happens automatically if this format is different from the format stored on the GPU. | 
| x | The starting x-coordinate, in pixels, of the Texture data to fetch. | 
| width | The width, in pixels, of the Texture data to fetch. | 
| y | The starting y-coordinate, in pixels, of the Texture data to fetch. | 
| height | The height, in pixels, of the Texture data to fetch. | 
| z | The starting z-coordinate, in pixels, of the Texture3D to fetch. For TextureCube, Texture2DArray, and TextureCubeArray, this is the index of the start layer. | 
| depth | The depth, in pixels of the Texture3D to fetch. For TextureCube, Texture2DArray, and TextureCubeArray, this is the number of layers to retrieve. | 
Retrieves data asynchronously from a GPU Texture resource.
| output | Reference to the NativeArray to write the data into. The NativeArray or underlying memory cannot be Disposed until the request is complete. | 
| src | The GraphicsBuffer to read the data from. | 
| size | The size, in bytes, of the data to retrieve from the GraphicsBuffer. | 
| offset | Offset in bytes in the GraphicsBuffer. | 
Retrieves data asynchronously from a GPU Graphics Buffer resource.
