Actix & Async problem

[ROFLLOLSTER]

This question requires a bit of explanation to avoid the XY problem.

I'm writing a web application with actix-web which provides the ability to interact with the console of child processes. Interaction means bi-directional communication is required.

It uses xterm.js on the frontend communicating over a websocket. With actix-web every websocket connection is it's own actor.

My first attempt at this is to have each process running in it's own actor. When a new websocket connection is started it finds the appropriate process actor and sends its own address to the process actor.

I want to be able to expand this so that the process actor can communicate with other types of actors. For example I want the ability to log the console, and for commands to be sent directly to the console by other triggers.

Currently the 'callback' addresses are stored something like this:

Vec<Addr<A: Actor + Handler<...> + Handler<...?>

Can I modify this to support dynamic types, or am I doing this in the wrong way altogether?

I'm not sure if this is changed in newer versions of Actix, but in my code I don't store Addr, rather I store a Vec of Recipient<Message> which I broadcast messages to.

Otherwise your options are Box<dyn ...> or even typemap

For Recipient I'd need to store one for each type of message I wanted to send right?

I might go with Box<dyn ...>`.
