//! Central fd-readiness reactor over the platform backends.
//!
//! The live path is fd readiness: I/O futures register wakers for a file
//! descriptor and interest, the platform backend (epoll/kqueue/`WSAPoll`)
//! reports readiness, and [`IoReactor`] wakes the registered executor wakers.
/// The [`IoReactor`] driving waker registration and event dispatch.
/// Reactor performance counters.
/// Thread-local / process-global active-reactor installation.
/// Reactor unit tests.
