Struct bastion::message::Answer [−][src]
A Future returned when successfully "asking" a
message using ChildRef::ask and which resolves to
a Result<Msg, ()> where the Msg is the message
answered by the child (see the msg! macro for more
information).
Example
// The message that will be "asked"... const ASK_MSG: &'static str = "A message containing data (ask)."; // The message the will be "answered"... const ANSWER_MSG: &'static str = "A message containing data (answer)."; // Create a new child... Bastion::children(|children| { children.with_exec(|ctx: BastionContext| { async move { // ...which will receive the message asked... msg! { ctx.recv().await?, msg: &'static str =!> { assert_eq!(msg, ASK_MSG); // Handle the message... // ...and eventually answer to it... answer!(ctx, ANSWER_MSG); }; // This won't happen because this example // only "asks" a `&'static str`... _: _ => (); } Ok(()) } }) }).expect("Couldn't create the children group."); // Later, the message is "asked" to the child... let answer: Answer = ctx.ask(&child_ref.addr(), ASK_MSG).expect("Couldn't send the message."); // ...and the child's answer is received... msg! { answer.await.expect("Couldn't receive the answer."), msg: &'static str => { assert_eq!(msg, ANSWER_MSG); // Handle the answer... }; // This won't happen because this example // only answers a `&'static str`... _: _ => (); }
