//! PulseAudio FFI binding for the `libpulse-simple` system library.
//!
//! This crate does nothing more than offer a simple FFI binding to the C API of the [PulseAudio]
//! client system library, specifically the “simple” interface component only. Please note that
//! there is a “higher-level” binding available (the [`libpulse-simple-binding`] crate), built on
//! top of this, which offers a more Rust-oriented interface.
//!
//! Unlike the “higher-level” binding just mentioned, virtually no documentation is provided here.
//! Things that *are* documented here are typically only those directly re-exported by the
//! “higher-level” binding. Please see either the equivalent documentation in that, or the
//! documentation of the actual PulseAudio C header files, if you need documentation.
