auto_device_map

Runnable Rust SDK example auto_device_map.

/// Automatic device mapping for text and multimodal models.
///
/// Device mapping distributes model layers across available GPUs automatically.
/// This example shows both text and multimodal model usage with auto device mapping.
///
/// Run with: `cargo run --release --example auto_device_map -p mistralrs`
