Module differential_dataflow::trace::wrappers::frontier

Wrapper for frontiered trace.

Wraps a trace with since and upper frontiers so that all exposed timestamps are first advanced by the since frontier and restricted by the upper frontier. This presents a deterministic trace on the interval [since, upper), presenting only accumulations up to since (rather than partially accumulated updates) and no updates at times greater or equal to upper (even as parts of batches that span that time).
