Struct WeakControlHandle 

pub struct WeakControlHandle<RS> { /* private fields */ }

Implementations

impl<RS> WeakControlHandle<RS>

where RS: RequestStream,

pub fn use_control_handle<User, R>(&self, user: User) -> Option<R>

where User: FnOnce(RS::ControlHandle) -> R,

If the server endpoint is not unbound, calls user function with the control handle and propagates the return value. Otherwise, returns None.

Typically you can use it to send an event within the closure:

let control_handle = stream.control_handle();
let result = control_handle.use_control_handle(
    |control_handle| control_handle.send_my_event());
