will add dependency injection future?

same like :

struct Service{}
impl Service{
  pub fn println();
}

struct Bean{
     service:Option<RefCell<Service>>// this field is  dependency injection
}

impl Bean{
  pub fn doSomeThing(&mut self){
         // call the dependency injection service
         self.service.println()....
  }
}

let service=Service{}
let bean=Bean{}
actix.inject(service)
actix.inject(bean)
// when dependency injection finish,  call bean.doSomeThing() will success.

Would you please add some detail about the scenario where dependency injection can be beneficial? It would be great if you can list pros and cons.

• use dependency injection Reduce coupling

• Unified management struct, For example, I want to count all the http api that I use. just call actix.beans() get All struct, You can do some automated scanning task or job（Very useful for reducing manual coding effort, just like java spring swagger UI scan your http API,auto create Doc ）

• for cons， The downside is that the configuration has become complex
