Crate libp2p_identify

Expand description

Implementation of the Identify protocol.

This implementation of the protocol periodically exchanges Info messages between the peers on an established connection.

At least one identification request is sent on a newly established connection, beyond which the behaviour does not keep connections alive.

§Important Discrepancies

  • Using Identify with other protocols Unlike some other libp2p implementations, rust-libp2p does not treat Identify as a core protocol. This means that other protocols cannot rely upon the existence of Identify, and need to be manually hooked up to Identify in order to make use of its capabilities.


The Behaviour struct implements a NetworkBehaviour that negotiates and executes the protocol on every established connection, emitting Events.


  • Network behaviour that automatically identifies nodes periodically, returns information about them, and answers identify queries from other nodes.
  • Configuration for the identify::Behaviour.
  • Identify information of a peer sent in protocol messages.
