pub fn query_gpu_adapter(window: Option<&Window>) -> Vec<GPUAdapter>Expand description
Queries the available GPU’s GPUAdapter.
This is useful for checking the available GPU adapters on the system and the supported
graphics APIs, allowing you to choose the best GPU and graphics API for your application.
This function can be called from any thread.
