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).
