Module differential_dataflow::trace::implementations::ord

Trace and batch implementations based on sorted ranges.

The types and type aliases in this module start with either

• OrdVal: Collections whose data have the form (key, val) where key is ordered.
• OrdKey: Collections whose data have the form key where key is ordered.

Although OrdVal is more general than OrdKey, the latter has a simpler representation and should consume fewer resources (computation and memory) when it applies.

Structs

OrdKeyBatch	An immutable collection of update tuples, from a contiguous interval of logical times.
OrdKeyBuilder	A builder for creating layers from unsorted update tuples.
OrdKeyCursor	A cursor for navigating a single layer.
OrdValBatch	An immutable collection of update tuples, from a contiguous interval of logical times.
OrdValBuilder	A builder for creating layers from unsorted update tuples.
OrdValCursor	A cursor for navigating a single layer.

Type Definitions

OrdKeySpine	A trace implementation for empty values using a spine of hash-map batches.
OrdValSpine	A trace implementation using a spine of hash-map batches.
