+This module re-exports RSC runtime API provided by `react-server-dom/server.edge` and `react-server-dom/client.edge` such as:
 
 - `renderToReadableStream`: RSC serialization (React VDOM -> RSC stream)
 - `createFromReadableStream`: RSC deserialization (RSC stream -> React VDOM). This is also available on rsc environment itself. For example, it allows saving serailized RSC and deserializing it for later use.
