//! Binary links notation version 1: packets and the marker-point LiNo mapping.
//!
//! Wire specification and shared vectors live in `docs/protocol/` in the
//! repository. This module supplies codecs; transports supply their own framing.
//!
//! ```
//! use links_notation::binary::{parse_document, BinaryLinoCodec};
//! let document = parse_document("() ((1 1))")?;
//! let codec = BinaryLinoCodec::new();
//! let bytes = codec.encode(&document)?;
//! assert_eq!(codec.decode(&bytes)?, document);
//! # Ok::<(), links_notation::binary::BinaryError>(())
//! ```
