Enum PermanentGpuId 

pub enum PermanentGpuId {
    Pci {
        vendor_id: Option<u32>,
        device_id: u32,
        subsys_id: Option<u32>,
        revision: Option<u32>,
    },
    Pnp(String),
    Name(String),
    Single,
}

The stable part of a GpuId. Every adapter enumerate_gpus reports carries one.

Variants

Pci

PCI vendor/device, plus the subsystem/revision that distinguishes board variants.

Stable across restarts; two identical cards share it. None is a wildcard — ZED_DEVICE_ID names a device only.

Fields

vendor_id: Option<u32>

The PCI vendor id, or None when the id names a device only.

device_id: u32

The PCI device id.

subsys_id: Option<u32>

The PCI subsystem id, when the backend reports one.

revision: Option<u32>

The PCI revision, when the backend reports one.

Pnp(String)

The Windows PnP device instance id — the one documented persistent per-adapter identity. DXGI does not expose it; a later SetupAPI read fills it in.

Name(String)

The adapter/driver name, where the platform has nothing better. Best-effort: two identical cards share it.

Single

A platform with one GPU, or a backend that cannot enumerate: there is only “the GPU”.

Implementations

impl PermanentGpuId

pub fn matches(&self, other: &PermanentGpuId) -> bool

Whether an adapter’s permanent part is the one this id names.

An Option field that is None in self is a wildcard; one that is None in other and required by self does not match, because the backend cannot confirm it.

pub fn vendor_id(&self) -> Option<u32>

The PCI vendor id, when this id has one.

pub fn device_id(&self) -> Option<u32>

The PCI device id, when this id has one.
