Module device 

Metal device interface.

Corresponds to Metal/MTLDevice.hpp.

The Device represents a GPU that can execute Metal commands. Use the system_default function to get the default GPU, or copy_all_devices (macOS only) to enumerate all available GPUs.

Example

use mtl_gpu::device;

// Get the default GPU
let device = device::system_default().expect("no Metal device");
println!("Using GPU: {}", device.name());
