Struct OncePortHandle

Source

pub struct OncePortHandle<M: Message> { /* private fields */ }

Expand description

A one-shot port handle to which M-typed messages can be delivered.

Implementations§

Source §

impl<M: Message> OncePortHandle<M>

Source

pub fn port_id(&self) -> &PortId

This port’s ID.

Source

pub fn send(self, message: M) -> Result<(), MailboxSenderError>

Send a message to this port. The send operation will consume the port handle, as the port accepts at most one message.

Source §

impl<M: RemoteMessage> OncePortHandle<M>

Source

pub fn bind(self) -> OncePortRef<M>

Turn this handle into a ref that may be passed to a remote actor. The remote actor can then use the ref to send a message to the port. Creating a ref also binds the port, so that it is remotely writable.
