Module differential_dataflow::trace::cursor [−][src]
Traits and types for navigating order sequences of update tuples.
The Cursor trait contains several methods for efficiently navigating ordered collections
of tuples of the form (key, val, time, diff). The cursor is different from an iterator
both because it allows navigation on multiple levels (key and val), but also because it
supports efficient seeking (via the seek_key and seek_val methods).
