+//! A "prelude" for users of the `tokio` crate.
+//!
+//! This prelude is similar to the standard library's prelude in that you'll
+//! almost always want to import its entire contents, but unlike the standard
+//! library's prelude you'll have to do so manually:
+//!
+//! ```
+//! # #![allow(warnings)]
+//! use tokio::prelude::*;
+//! ```
+//!
+//! The prelude may grow over time as additional items see ubiquitous use.

+    #[doc(no_inline)]
