Zero-Copy Streaming from Hyper and h3-quinn into Wasmtime WASI Components

A developer building a high-performance API gateway seeks to minimize memory copying when streaming data from hyper and h3-quinn into Wasmtime WASI components via wasi:http. The challenge involves bridging buffer ownership, adapting stream abstractions, and propagating backpressure across the sandbox boundary. The post asks for architectural patterns to achieve zero-copy data paths without CPU-based memcpy.
