Module differential_dataflow::trace::implementations::ord_neu

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.
• OrdValBatch
  An immutable collection of update tuples, from a contiguous interval of logical times.
• OrdValBuilder
  A builder for creating layers from unsorted update tuples.

Type Aliases

• ColKeySpine
  A trace implementation backed by columnar storage.
• ColValSpine
  A trace implementation backed by columnar storage.
• OrdKeySpine
  A trace implementation using a spine of ordered lists.
• OrdValSpine
  A trace implementation using a spine of ordered lists.
• PreferredSpine
  A trace implementation backed by columnar storage.
