//! Module with system specific types.
//!
//! Required types:
//!
//! * `Event`: a type alias for the system specific event, e.g. `kevent` or
//! `epoll_event`.
//! * `event`: a module with various helper functions for `Event`, see
//! [`crate::event::Event`] for the required functions.
//! * `Events`: collection of `Event`s, see [`crate::Events`].
//! * `IoSourceState`: state for the `IoSource` type.
//! * `Selector`: selector used to register event sources and poll for events,
//! see [`crate::Poll`] and [`crate::Registry`] for required
//! methods.
//! * `tcp` and `udp` modules: see the [`crate::net`] module.
//! * `Waker`: see [`crate::Waker`].
