//
//! Asynchronous cross-platform real-time audio recording & playback.
//!
//! # Getting Started
//! Add the following to your *Cargo.toml*:
//!
//! ```toml
//! [dependencies]
//! pasts = "0.7"
//! wavy = "0.8"
//! fon = "0.4"
//! ```
//!
//! This example records audio and plays it back in real time as it's being
//! recorded.  (Make sure to wear headphones to avoid feedback):
//!
//! ```rust,no_run
//! use fon::{stereo::Stereo32, Sink, Audio};
//! use pasts::{exec, wait};
//! use wavy::{Speakers, Microphone, SpeakersSink, MicrophoneStream};
//!
//! /// An event handled by the event loop.
//! enum Event<'a> {
//!     /// Speaker is ready to play more audio.
//!     Play(SpeakersSink<'a, Stereo32>),
//!     /// Microphone has recorded some audio.
//!     Record(MicrophoneStream<'a, Stereo32>),
//! }
//!
//! /// Shared state between tasks on the thread.
//! struct State {
//!     /// Temporary buffer for holding real-time audio samples.
//!     buffer: Audio<Stereo32>,
//! }
//!
//! impl State {
//!     /// Event loop.  Return false to stop program.
//!     fn event(&mut self, event: Event<'_>) {
//!         match event {
//!             Event::Play(mut speakers) => speakers.stream(self.buffer.drain()),
//!             Event::Record(microphone) => self.buffer.extend(microphone),
//!         }
//!     }
//! }
//!
//! /// Program start.
//! fn main() {
//!     let mut state = State { buffer: Audio::with_silence(48_000, 0) };
//!     let mut speakers = Speakers::default();
//!     let mut microphone = Microphone::default();
//!
//!     exec!(state.event(wait! {
//!         Event::Record(microphone.record().await),
//!         Event::Play(speakers.play().await),
//!     }));
//! }
//! ```
