[Rust] How to store and reuse `Doc<>` struct in my application?

Overview:

• The README.md example snippets shows how to create a Docs<Store> struct in rust

let docs: Docs<Store> = Docs::memory().spawn(&blobs, &gossip).await?;

• However, when I create a client, and a document, the rust types for these structs are complex, part of it is even private i.e. quic-rpc / Connection

    let docs_client = docs.client();
    let doc = docs_client.create().await?;

I'm running into the following issue:

• It is not clear, what is the intended lifecycle of these structs.
  • Should I save the instance and passing them around my applications's struct/function to implement my logic? (Complicated typing leads to compiler headaches)
  • Or treat them as one-off instance, and instead clone the Docs<Store> struct & NamespaceID, then uses it to spawn in the document client when ever needed. (Seems to not be ideal, performance wise)

Start with the README.md Rust example using Docs::memory().spawn, then inspect the docs.client() and create() entry points mentioned in the issue. Clarify the intended lifecycle and reusable application-facing types for Docs, the client, and NamespaceID, and document the guidance in the README.
