+//! The [`transport`] module contains a fully featured HTTP/2.0 [`Channel`] (gRPC terminology)
+//! and [`Server`]. These implementations are built on top of [`tokio`], [`hyper`] and [`tower`].
+//! It also provides many of the features that the core gRPC libraries provide such as load balancing,

+//! to build even more feature rich clients and servers. This module also provides the ability to choose
