Struct timely::dataflow::channels::pushers::exchange::Exchange

pub struct Exchange<T, CB, P, H>
where
    CB: ContainerBuilder,
    CB::Container: SizableContainer,
    P: Push<Message<T, CB::Container>>,
    for<'a> H: FnMut(&<CB::Container as Container>::Item<'a>) -> u64,
{ /* private fields */ }

Distributes records among target pushees according to a distribution function.

Implementations

impl<T: Clone, CB, P, H> Exchange<T, CB, P, H>

where CB: ContainerBuilder, CB::Container: SizableContainer, P: Push<Message<T, CB::Container>>, for<'a> H: FnMut(&<CB::Container as Container>::Item<'a>) -> u64,

pub fn new(pushers: Vec<P>, key: H) -> Exchange<T, CB, P, H>

Allocates a new Exchange from a supplied set of pushers and a distribution function.

Trait Implementations

impl<T: Eq + Data, CB, P, H> Push<Message<T, <CB as ContainerBuilder>::Container>> for Exchange<T, CB, P, H>

where CB: ContainerBuilder + for<'a> PushInto<<CB::Container as Container>::Item<'a>>, CB::Container: SizableContainer, P: Push<Message<T, CB::Container>>, for<'a> H: FnMut(&<CB::Container as Container>::Item<'a>) -> u64,

fn push(&mut self, message: &mut Option<Message<T, CB::Container>>)

Pushes element with the opportunity to take ownership.

fn send(&mut self, element: T)

Pushes element and drops any resulting resources.

fn done(&mut self)

Pushes None, conventionally signalling a flush.
