Num Stream
This crate provides a Stream that yields numeric values at a specifed interval and that increments at a specifed rate.
This crate was born out of the desire for a simple configurable stream that would yield ever changing, yet predictable values.
The num_stream method can be used to acquire an instance of a NumStream struct which implements a Futures 0.3 Stream.
