//! The half of a Vector call that runs anywhere: the wire format, the jitter buffer,
//! the rate ladder, and the small signal-processing pieces that need no device.
//! Everything that touches a microphone, a speaker, a codec library or a socket
//! lives in the client that embeds this crate.
//!
//! No clock: every function that reasons about time takes milliseconds in, so the
//! same code runs under tokio, on a thread, and in a browser.
