vector_calls/lib.rs
1//! The half of a Vector call that runs anywhere: the wire format, the jitter buffer,
2//! the rate ladder, and the small signal-processing pieces that need no device.
3//! Everything that touches a microphone, a speaker, a codec library or a socket
4//! lives in the client that embeds this crate.
5//!
6//! No clock: every function that reasons about time takes milliseconds in, so the
7//! same code runs under tokio, on a thread, and in a browser.
