### Is there an existing issue for this? - [x] I have searched the existing issues ### Description **Description:** [Documentation](https://developers.cloudflare.com/workers/runtime-apis/rpc/#readablestream-writeablestream-request-and-response) states "You can send and receive [ReadableStream](https://developers.cloudflare.com/workers/runtime-apis/streams/readablestream/), [WriteableStream](https://developers.cloudflare.com/workers/runtime-apis/streams/writablestream/), [Request](https://developers.cloudflare.com/workers/runtime-apis/request/), and [Response](https://developers.cloudflare.com/workers/runtime-apis/response/) using RPC methods". How can I implement these stream types via RPC methods in Rust? **Expectations:** - Detailed code example showing how to create a ReadableStream in Rust RPC - Demonstrate how to send and receive streams between client and server - Provide a complete working example with server and client code **Related Issues:** No access to Env in #[wasm_bindgen] RPC functions #720
