Enum DeviceId 

pub enum DeviceId {
    Cpu,
    VulkanUuid([u8; 16]),
    CudaUuid([u8; 16]),
    DxgiLuid {
        high: i32,
        low: u32,
    },
    MetalRegistryId(u64),
    OpenCl {
        platform: String,
        device: String,
    },
}

Stable identity of a physical GPU / CPU / accelerator. Used as cache key in multi-GPU setups and as an equality test for Error::DeviceMismatch.

Variants

Cpu

The host CPU pseudo-device — the target of the CPU fallback backend. A single canonical identity (the host has one logical CPU compute target from the library’s perspective), so it carries no payload and all CPU devices compare equal.
