Trait Partition 

pub trait Partition<G: Scope, D: 'static> {
    // Required method
    fn partition<D2: 'static, F: Fn(D) -> (u64, D2) + 'static>(
        self,
        parts: u64,
        route: F,
    ) -> Vec<StreamVec<G, D2>> ;
}

Partition a stream of records into multiple streams.

Required Methods

fn partition<D2: 'static, F: Fn(D) -> (u64, D2) + 'static>( self, parts: u64, route: F, ) -> Vec<StreamVec<G, D2>>

Produces parts output streams, containing records produced and assigned by route.

Examples

use timely::dataflow::operators::{ToStream, Inspect, vec::Partition};

timely::example(|scope| {
    let mut streams = (0..10).to_stream(scope)
                             .partition(3, |x| (x % 3, x));

    streams.pop().unwrap().inspect(|x| println!("seen 2: {:?}", x));
    streams.pop().unwrap().inspect(|x| println!("seen 1: {:?}", x));
    streams.pop().unwrap().inspect(|x| println!("seen 0: {:?}", x));
});

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
