4//! This crate provides a set of types that abstract over OS-specific platform
5//! primitives. It is focused on IO- and wait-related functionality: events,
6//! timers, and polling.
7//!
8//! As a convenience, it also exports some OS-specific functionality and some
9//! general library functionality.
