Module differential_dataflow::operators

Specialize differential dataflow operators.

Differential dataflow introduces a small number of specialized operators on collections. These operators have specialized implementations to make them work efficiently, and are in addition to several operations defined directly on the Collection type (e.g. map and filter).

Modules

arrange	Types and traits for arranging collections.
consolidate	Aggregates the weights of equal records into at most one record.
count	Group records by a key, and apply a reduction function.
