Enum DevicePreference 

pub enum DevicePreference {
    Auto,
    Cpu,
    Gpu {
        index: Option<u32>,
    },
    Explicit {
        device_type: DeviceType,
        index: u32,
    },
}

Intent-based device preference (§20.4). The runtime maps this to concrete EPs during build.

Variants

Auto

Pick the best available device automatically.

Cpu

Prefer CPU execution.

Gpu

Prefer a GPU / accelerator, optionally by ordinal.

Fields

index: Option<u32>

Explicit

Pin to a specific device class + ordinal.

Fields

device_type: DeviceType

index: u32
