Renamed APIs * Loop => reactor::Core * LoopHandle => reactor::Handle * LoopPin => reactor::Pinned * TcpStream => net::TcpStream * TcpListener => net::TcpListener * UdpSocket => net::UdpSocket * Sender => channel::Sender * Receiver => channel::Receiver * Timeout => reactor::Timeout * ReadinessStream => reactor::PollEvented * All `LoopHandle` methods to construct objects are now free functions on the associated types, e.g. `LoopHandle::tcp_listen` is now `TcpListener::bind` * All APIs taking a `Handle` now take a `Handle` as the last argument * All future-returning APIs now return concrete types instead of trait objects Added APIs * io::Io trait -- Read + Write + ability to poll Removed without replacement: * AddSource * AddTimeout * IoToken * TimeoutToken Closes #3 Closes #6
