//! Driver for VirtIO socket devices.
//!
//! To use the driver, you should first create a [`VirtIOSocket`] instance with your VirtIO
//! transport, and then create a [`VsockConnectionManager`] wrapping it to keep track of
//! connections. If you want to manage connections yourself you can use the `VirtIOSocket` directly
//! for a lower-level interface.
//!
//! See [`VsockConnectionManager`] for a usage example.
