Struct timely::dataflow::operators::generic::OutputHandleCore

pub struct OutputHandleCore<'a, T: Timestamp, C: Container + 'a, P: Push<Bundle<T, C>> + 'a> { /* private fields */ }

Handle to an operator’s output stream.

Implementations

impl<'a, T: Timestamp, C: Container, P: Push<Bundle<T, C>>> OutputHandleCore<'a, T, C, P>

pub fn session<'b, CT: CapabilityTrait<T>>( &'b mut self, cap: &'b CT ) -> Session<'b, T, C, PushCounter<T, C, 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::Operator;
use timely::dataflow::channels::pact::Pipeline;

timely::example(|scope| {
    (0..10).to_stream(scope)
           .unary(Pipeline, "example", |_cap, _info| |input, output| {
               input.for_each(|cap, data| {
                   let time = cap.time().clone() + 1;
                   output.session(&cap.delayed(&time))
                         .give_vec(&mut data.replace(Vec::new()));
               });
           });
});

pub fn cease(&mut self)

Flushes all pending data and indicate that no more data immediately follows.
