Struct DeviceOptions 

#[non_exhaustive]
pub struct DeviceOptions {
    pub compute_queue: bool,
}

(G5d) what Adapter::create_device_with sets up beyond DeviceDesc; DEFAULT is what create_device does. Fields may come in later versions: start from DEFAULT

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

compute_queue: bool

a queue of its own for compute and copies (Device::compute_queue): Vulkan, where the device has a family without graphics. Then every buffer and every texture that is no render target is shared by both queues’ families (concurrently), which some GPUs may pay for; off by default, and jfgui_GPU_COMPUTE=0 turns it off
