Struct heph_inbox::Manager [−][src]
Manager of a channel.
A channel manager can be used to create Sender
s and Receiver
s 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>
[src]
pub fn new_small_channel() -> (Manager<T>, Sender<T>, Receiver<T>)
[src]
Create a small bounded channel with a Manager
.
Same as new_small
but with a Manager
.
pub fn new_sender(&self) -> Sender<T>
[src]
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>
[src]
Attempt to create a new Receiver
.
This will fail if there already is a receiver.
