how to spawn a thread in main or other place only once

[jiker-burce]

Problem

Steps To Reproduce

Steps to reproduce the behavior:

fn main() {
launch(client_mod::client_lib::Client);
}

pub fn Client() -> Element {
    println!("Client");

  spawn(async move {
  // do some async things here
  }
}

• I found that if something changed, the Client(main App component) will be rendered again, so the Client will be printed many times. So that the spawn will generate many times.

Expected behavior
Is there a way could spawn new thread in fn main or other places, so I could just spawn a new thread once just like launch().

We have use_future, use_effect, and use_hook depending on how much abstraction you need.

@jkelleyrtp thanks for the reply. but I found that to use the spawn() in the top element fn() could solve the problem. We should move the values that would be rerendered in the child component.
