Struct timely::dataflow::operators::generic::InputHandle [−][src]
Handle to an operator’s input stream.
Implementations
impl<'a, T: Timestamp, D: Data, P: Pull<Bundle<T, D>>> InputHandle<T, D, P>
[src]
pub fn next(&mut self) -> Option<(CapabilityRef<'_, T>, RefOrMut<'_, Vec<D>>)>
[src]
Reads the next input buffer (at some timestamp t
) and a corresponding capability for t
.
The timestamp t
of the input buffer can be retrieved by invoking .time()
on the capability.
Returns None
when there’s no more data available.
pub fn for_each<F: FnMut(CapabilityRef<'_, T>, RefOrMut<'_, Vec<D>>)>(
&mut self,
logic: F
)
[src]
&mut self,
logic: F
)
Repeatedly calls logic
till exhaustion of the available input data.
logic
receives a capability and an input buffer.
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| { output.session(&cap).give_vec(&mut data.replace(Vec::new())); }); }); });
