//! The PeerManager module is responsible for establishing connections between Peers and for
//! opening/receiving new substreams on those connections.
//!
//! ## Implementation
//!
//! The PeerManager is implemented as a number of actors:
//!  * A main event loop actor which is responsible for handling requests and sending
//!  notification about new/lost Peers to the rest of the network stack.
//!  * An actor responsible for dialing and listening for new connections.
