Struct timely::dataflow::operators::generic::OutputHandle

pub struct OutputHandle<'a, T: Timestamp, D: 'a, P: Push<(T, Content<D>)> + 'a> { /* fields omitted */ }

Handle to an operator's output stream.

Methods

impl<'a, T: Timestamp, D, P: Push<(T, Content<D>)>> OutputHandle<'a, T, D, P>

fn session<'b>(
    &'b mut self,
    cap: &'b Capability<T>
) -> Session<'b, T, D, PushCounter<T, D, P>> where
    'a: 'b, 

Obtains a session that can send data at the timestamp associated with capability cap.

In order to send data at a future timestamp, obtain a capability for the new timestamp first, as show in the example.

Examples

use timely::dataflow::operators::ToStream;
use timely::dataflow::operators::generic::unary::Unary;
use timely::dataflow::channels::pact::Pipeline;

timely::example(|scope| {
    (0..10).to_stream(scope)
           .unary_stream(Pipeline, "example", |input, output| {
               input.for_each(|cap, data| {
                   let mut time = cap.time().clone();
                   time.inner += 1;
                   output.session(&cap.delayed(&time)).give_content(data);
               });
           });
});
