Central app controller for back end when using SSR (actix or axum)

[maartensson]

I am fairly new to rust and SSR

I normally develop back end applications in golang using hexagonal architechture with ports and injection keeping everything separated and modular.

for instance if I have a back end with some http endpoints I would inject the application into the http implementation and I would have a reference to my application from there.

type App struct {
    db *DB
}

type HttpEdge struct {
    app App
}

func NewHttpEdge(app *App) *HttpEdge {
    return &HttpEdge{ app }
}

func (api *HttpEdge) rootEndpoint(w http.ResponseWriter, r *http.Response) {
    // Here I can access my app
    api.app.SomeFunction() 
}

My question is how can I do something like this with axtix or axum? I saw in the "auth with session example" that an auth()? function was called to access some shared object but it did not make any sense to me where the instance is running and who is allowed to access it.

I would like to use this for calling grpc services and maybe for some auththentication logic as well.

I think you might be looking for something like Axum's State or Actix's Data, both of which allow a kind of dependency injection, but to be fair I have never heard the term hexagonal architecture, don't know Go, and have no real idea what you're talking about.

I think this might be a more general Rust/Axum/Actix question though so you may also have luck asking in communities dedicated to those.

Thank you! I will look at State and Data
