Expand description

A convenience for futures that return Result values that includes a variety of adapters tailored to such futures.

The type of failures yielded by this future

Required Methods

Poll this TryFuture as if it were a Future.

This method is a stopgap for a compiler limitation that prevents us from directly inheriting from the Future trait; in the future it won’t be needed.
