Struct capnp_futures::Sender

pub struct Sender<M> where
    M: AsOutputSegments,  { /* fields omitted */ }

A handle that allows message to be sent to a write queue`.

Implementations

impl<M> Sender<M> where
    M: AsOutputSegments, 

pub fn send(
    &mut self,
    message: M
) -> impl Future<Output = Result<M, Error>> + Unpin

Enqueues a message to be written. The returned future resolves once the write has completed.

pub fn len(&mut self) -> usize

Returns the number of messages queued to be written, not including any in-progress write.

pub fn terminate(
    &mut self,
    result: Result<(), Error>
) -> impl Future<Output = Result<(), Error>> + Unpin

Commands the queue to stop writing messages once it is empty. After this method has been called, any new calls to send() will return a future that immediately resolves to an error. If the passed-in result is an error, then the WriteQueue will resolve to that error.

Trait Implementations

impl<M> Clone for Sender<M> where
    M: AsOutputSegments, 

fn clone(&self) -> Sender<M>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
