Enum DeviceLostReason 

pub enum DeviceLostReason {
    Removed,
    Reset,
    Hung,
    SurfaceLost,
    Unknown,
}

Why the GPU device stopped servicing work, as reported by the backend API.

Variants

Removed

The physical device left (unplugged eGPU, driver upgrade teardown).

Reset

The device reset underneath the app (TDR without a hang verdict).

Hung

The OS killed the device after deciding our workload hung it.

SurfaceLost

The presentation surface died; the device may be healthy, but the backend cannot present without recreating the surface.

Unknown

The backend reported loss without a usable reason code.
