Struct capnp_futures::Sender

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

A handle that allows message to be sent to a WriteQueue.

Methods

impl<M> Sender<M> where     M: AsOutputSegments + 'static,

pub fn send(&mut self, message: M) -> Box<Future<Item = M, Error = Error>>

Enqueues a message to be written.

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> ) -> Box<Future<Item = (), Error = Error>>

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.

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