Is there a way to get the number of sockets connected in a dynamic namespace ??

[Axnjr]

let io_clone - io.clone();
let _ = io.dyn_ns("/{client_id}", |s: SocketRef| async move {
      let auth_token = s.ns().to_string();
      let namespace_size = io_clone.of(&auth_token[1..]).unwrap().sockets().unwrap().len(); // pls help !!
// ..........
});

If you want to get the number of sockets for this namespace variant:

let _ = io.dyn_ns("/{client_id}", |s: SocketRef, io: SocketIo| async move {
      let namespace_size = io.of(s.ns()).unwrap().sockets().unwrap().len(); // this should work
});

But if you want all the sockets of all the namespaces variants corresponding to this dynamic namespace, you can't. Currently dynamic namespace features are quite limited. It will be added to the roadmap though.

It is a bit hacky but can maintain an external counter or a set of the created namespaces and fetch + sum the number of sockets for each namespace.

Btw you can use SocketIo as a param extractor rather than cloning it:

let _ = io.dyn_ns("/{client_id}", |s: SocketRef, io: SocketIo| async move {
      let auth_token = s.ns().to_string();
      let namespace_size = io.of(&auth_token[1..]).unwrap().sockets().unwrap().len(); // pls help !!
// ..........
});

ahh ok,
thanks for telling about the param extraction method :)

hope this feature is added soon !!
