rlx-driver

Driver layer for RLX — Device enum + cross-cutting types (arenas, buffers, command streams).

This crate sits between rlx-ir (vocabulary) and the per-backend crates (execution). Backends consume the types here so the runtime can dispatch to any of them through a uniform interface.

What's here

• Device — Cpu, Metal, Mlx, Ane, Cuda, Rocm, Tpu, Gpu (wgpu), Vulkan, OpenGl, DirectX, WebGpu, Fpga. Used by the runtime to pick a backend and by tests to pin graphs to a specific path.
• registry — process-global table of which Device variants have a registered backend (set at runtime, queried by rlx_runtime::Device::is_available).
• Collective primitives — the Transport trait + ProcessGroup (all_reduce / all_gather / broadcast / barrier) with TcpTransport (mesh) and NetTransport (star) for distributed / multi-stream scenarios that the runtime composes on top.
• IrohTransport (feature iroh) — a NAT-traversing Transport over iroh QUIC (relays + pkarr/DNS discovery): ranks addressed by EndpointId, no ip:port. See ../../../docs/iroh-transport.md.
