Function get_device 

pub fn get_device(config: &DeviceConfig) -> Result<Device>

Get a device according to configuration, preferring CUDA.

This function implements the CUDA-first philosophy:

1. If force_cpu is set, returns CPU device with warning
2. Otherwise, attempts to get CUDA device at specified ordinal
3. Falls back to CPU with warning if CUDA unavailable

Arguments

• config - Device configuration specifying preferences

Returns

The selected Candle Device.

Errors

Returns error only if device creation fails entirely (rare).

Example

use rust_ai_core::{get_device, DeviceConfig};

let device = get_device(&DeviceConfig::from_env())?;
println!("Using device: {:?}", device);
