# 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** — types for distributed / multi-stream
  scenarios that the runtime composes on top.

## Install
