Trait timely::dataflow::operators::exchange::Exchange

pub trait Exchange<D: Data> {
    fn exchange<F: Fn(&D) -> u64 + 'static>(&self, route: F) -> Self;
}

Exchange records between workers.

Required Methods

fn exchange<F: Fn(&D) -> u64 + 'static>(&self, route: F) -> Self

Exchange records so that all records with the same route are at the same worker.

Examples

use timely::dataflow::operators::{ToStream, ExchangeExtension, Inspect};

timely::example(|scope| {
    (0..10).to_stream(scope)
           .exchange(|&x| x)
           .inspect(|x| println!("seen: {:?}", x));
});
