Emu is a Rust GPGPU library providing a CUDA-like compute-focused abstraction over WebGPU. It offers type-safe GPU data boxing, an auto-managed device pool, and JIT-compiled compute kernels that run across Vulkan, Metal, and DirectX backends.

Use cases

• run GPU compute kernels portably across Vulkan, Metal, and DirectX
• accelerate heavy computations in Rust without writing vendor-specific CUDA code
• box and move typed data to and from the GPU safely
• cache JIT-compiled compute kernels with an LRU cache
• mix compute workloads with WebGPU-based graphics code
• eventually run GPU compute in the browser via WebAssembly

When to choose

• you want CUDA-style GPU computing in Rust with cross-platform portability
• you need a transparent abstraction you can drop out of to raw WebGPU when needed
• you want asynchronous, non-blocking GPU data transfers with type safety

When to avoid

• you need mature, actively developed tooling or long-term support
• you need graphics rendering rather than compute workloads
• you require cutting-edge WebGPU features or browser support today
