RFnOnce

remoc::rfn

Struct RFnOnce 

Source 
pub struct RFnOnce<A, R, Codec = Default> { /* private fields */ }
Available on crate feature rfn only.
Expand description

Calls an async FnOnce function possibly located on a remote endpoint.

The function can take between zero and ten arguments.

§Example

In the following example the server sends a remote function that returns a string that is moved into the closure. The client receives the remote function and calls it.

use remoc::prelude::*;

type GetRFnOnce = rfn::RFnOnce<(), Result<String, rfn::CallError>>;

// This would be run on the client.
async fn client(mut rx: rch::base::Receiver<GetRFnOnce>) {
    let mut rfn_once = rx.recv().await.unwrap().unwrap();
    assert_eq!(rfn_once.call().await.unwrap(), "Hallo".to_string());
}

// This would be run on the server.
async fn server(mut tx: rch::base::Sender<GetRFnOnce>) {
    let msg = "Hallo".to_string();
    let func = || async move { Ok(msg) };
    let rfn_once = rfn::RFnOnce::new_0(func);
    tx.send(rfn_once).await.unwrap();
}
