Struct LateBoundSender

Source
pub struct LateBoundSender<S> { /* private fields */ }
Expand description

Sometimes we want to be able to pass in a sender that has not yet been fully constructed. LateBoundSender can act as a placeholder to pass CanSend and CanSendAsync capabilities through to the inner object. bind() should be called when the inner object is ready. All calls to send() and send_async() through this wrapper will block until bind() is called.

Example: let late_bound = LateBoundSender::new(); let something_else = SomethingElse::new(late_bound.as_sender()); let implementation = Implementation::new(something_else); late_bound.bind(implementation);
