we're acquiring this twice now we could do the this combined in an if let else

by checking this.inner.read().await.cloned()

also the write check still has a race condition, so we also need to check for is_none there again

I don't think we even need to clone since Service is implemented for &Http and &Pubsub

ah right, it works as long as we can obtain &mut &T

match this.inner.read().await.as_ref().unwrap() {
    InnerTransport::Http(http) => {
        let mut http = http;
        http.call(req)
    },
}

is there a cleaner way to do this without that strange let?

Don't think so

refactored it, now we don't clone and check second time after aquiring write lock

we can't use if let some there anymore I believe because we don't clone

can do InnerTransport::Http(mut http)?

mut http removes the reference

error[E0507]: cannot move out of a shared reference

    |                   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    |                                      data moved here
    |                                      move occurs because `http` has type `alloy_transport_http::Http<reqwest::Client>`, which does not implement the `Copy` trait

help: consider borrowing the pattern binding

And ref mut creates &mut T when we want &mut &T. This looks like a weird case that's not covered by patterns ig

InnerTransport::Http(mut http) => http.call(req),
InnerTransport::Ws(mut ws) => ws.call(req),
InnerTransport::Ipc(mut ipc) => ipc.call(req),
}
.await
})
