pub struct IpcReceiverSet { /* private fields */ }
Expand description

Collection of IpcReceivers moved into the set; thus creating a common (and exclusive) endpoint for receiving messages on any of the added channels.

Examples

let data = vec![0x52, 0x75, 0x73, 0x74, 0x00];
let (tx, rx) = ipc::channel().unwrap();
let mut rx_set = IpcReceiverSet::new().unwrap();

// Add the receiver to the receiver set and send the data
// from the sender
let rx_id = rx_set.add(rx).unwrap();
tx.send(data.clone()).unwrap();

// Poll the receiver set for any readable events
for event in rx_set.select().unwrap() {
    match event {
        IpcSelectionResult::MessageReceived(id, message) => {
            let rx_data: Vec<u8> = message.to().unwrap();
            assert_eq!(id, rx_id);
            assert_eq!(data, rx_data);
            println!("Received: {:?} from {}...", data, id);
        },
        IpcSelectionResult::ChannelClosed(id) => {
            assert_eq!(id, rx_id);
            println!("No more data from {}...", id);
        }
    }
}

Implementations

Create a new empty IpcReceiverSet.

Receivers may then be added to the set with the add method.

Add and consume the IpcReceiver to the set of receivers to be polled. IpcReceiver: struct.IpcReceiver.html

Add an OpaqueIpcReceiver to the set of receivers to be polled. OpaqueIpcReceiver: struct.OpaqueIpcReceiver.html

Wait for IPC messages received on any of the receivers in the set. The method will return multiple events. An event may be either a message received or a channel closed event.
