[][src]Struct constellation::Receiver

pub struct Receiver<T: DeserializeOwned>(_, _);

The receiving half of a channel.

It has an async method recv() and a nonblocking method try_recv().

For blocking behaviour use .recv().block().

Methods

impl<T: DeserializeOwned> Receiver<T>[src]

pub fn new(remote: Pid) -> Self[src]

Create a new Receiver<T> with a remote Pid. This method returns instantly.

pub fn remote_pid(&self) -> Pid[src]

Get the pid of the remote end of this Receiver.

pub fn try_recv<'a>(
    &'a self
) -> Option<impl FnOnce() -> Result<T, ChannelError> + 'a> where
    T: 'static, 
[src]

Nonblocking recv.

If receiving would not block, Some is returned with a FnOnce that returns a Result<T, ChannelError>. If receiving would block, None is returned.

pub async fn recv<'_>(&'_ self) -> Result<T, ChannelError> where
    T: 'static, 
[src]

Receive.

This is an async fn.
