Sender end of a channel to interface with a subsystem.
Required Methods§
sourcefn send_message<'life0, 'async_trait>(
&'life0 mut self,
msg: OutgoingMessage
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
'life0: 'async_trait,
Self: 'async_trait,
fn send_message<'life0, 'async_trait>(
&'life0 mut self,
msg: OutgoingMessage
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
'life0: 'async_trait,
Self: 'async_trait,
Send a direct message to some other Subsystem, routed based on message type.
sourcefn try_send_message(
&mut self,
msg: OutgoingMessage
) -> Result<(), TrySendError<OutgoingMessage>>
fn try_send_message( &mut self, msg: OutgoingMessage ) -> Result<(), TrySendError<OutgoingMessage>>
Tries to send a direct message to some other Subsystem, routed based on message type.
This method is useful for cases where the message queue is bounded and the message is ok
to be dropped if the queue is full. If the queue is full, this method will return an error.
This method is not async and will not block the current task.
sourcefn send_messages<'life0, 'async_trait, I>(
&'life0 mut self,
msgs: I
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
'life0: 'async_trait,
I: IntoIterator<Item = OutgoingMessage> + Send + 'async_trait,
<I as IntoIterator>::IntoIter: Send,
Self: 'async_trait,
fn send_messages<'life0, 'async_trait, I>(
&'life0 mut self,
msgs: I
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
'life0: 'async_trait,
I: IntoIterator<Item = OutgoingMessage> + Send + 'async_trait,
<I as IntoIterator>::IntoIter: Send,
Self: 'async_trait,
Send multiple direct messages to other Subsystems, routed based on message type.
sourcefn send_unbounded_message(&mut self, msg: OutgoingMessage)
fn send_unbounded_message(&mut self, msg: OutgoingMessage)
Send a message onto the unbounded queue of some other Subsystem, routed based on message
type.
This function should be used only when there is some other bounding factor on the messages sent with it. Otherwise, it risks a memory leak.
Object Safety§
This trait is not object safe.
