21//! Implementation of the [Identify](https://github.com/libp2p/specs/blob/master/identify/README.md) protocol.
22//!
23//! This implementation of the protocol periodically exchanges
24//! [`Info`] messages between the peers on an established connection.
25//!
26//! At least one identification request is sent on a newly established
27//! connection, beyond which the behaviour does not keep connections alive.
28//!
29//! # Important Discrepancies
30//!
31//! - **Using Identify with other protocols** Unlike some other libp2p implementations, rust-libp2p
32//!   does not treat Identify as a core protocol. This means that other protocols cannot rely upon
33//!   the existence of Identify, and need to be manually hooked up to Identify in order to make use
34//!   of its capabilities.
35//!
36//! # Usage
37//!
38//! The [`Behaviour`] struct implements a [`NetworkBehaviour`](libp2p_swarm::NetworkBehaviour)
39//! that negotiates and executes the protocol on every established connection, emitting
40//! [`Event`]s.
