Module timely::dataflow::operators

Extension traits for Stream implementing various operators.

A collection of functions taking typed Stream objects as input and producing new Stream objects as output. Many of the operators provide simple, composable functionality. Some of the operators are more complicated, for use with advanced timely dataflow features.

The Operator trait provides general operators whose behavior can be supplied using closures accepting input and output handles. Most of the operators in this module are defined using these two general operators.
