Struct Manager 

pub struct Manager<T> { /* private fields */ }

Manager of a channel.

A channel manager can be used to create Senders and Receivers for a channel, without having access to either. Its made for the following use case: restarting an actor which takes ownership of the Receiver and crashes, and to restart the actor we need another Receiver. Using the manager a new Receiver can be created, ensuring only a single Receiver is alive at any given time.

Implementations

impl<T> Manager<T>

pub fn new_small_channel() -> (Manager<T>, Sender<T>, Receiver<T>)

Create a small bounded channel with a Manager.

Same as new_small but with a Manager.

pub fn new_channel(capacity: usize) -> (Manager<T>, Sender<T>, Receiver<T>)

Create a bounded channel with a Manager.

Same as new but with a Manager.

pub fn new_sender(&self) -> Sender<T>

Create a new Sender.

Safety

See the safety nodes on Sender’s Clone implemenation, the same conditions apply here.

pub fn new_receiver(&self) -> Result<Receiver<T>, ReceiverConnected>

Attempt to create a new Receiver.

This will fail if there already is a receiver.
