Promising Future
This crate implements Promise
s and Future
s, where a Future
represents an unknown value, and a Promise
determines what that
value is.
It also provides FutureStream
which allows multiple Future
s to be
waited on, yielding values as they become available.
While this could be seen as a "yet another" crate, the API both simpler and more general than other implementations of Futures, and more easily composable.
