//! Transports, upgrades, multiplexing and node handling of *libp2p*.
//!
//! The main concepts of libp2p-core are:
//!
//! - A [`PeerId`] is a unique global identifier for a node on the network.
//! Each node must have a different [`PeerId`]. Normally, a [`PeerId`] is the
//! hash of the public key used to negotiate encryption on the
//! communication channel, thereby guaranteeing that they cannot be spoofed.
//! - The [`Transport`] trait defines how to reach a remote node or listen for
//! incoming remote connections. See the [`transport`] module.
//! - The [`StreamMuxer`] trait is implemented on structs that hold a connection
//! to a remote and can subdivide this connection into multiple substreams.
//! See the [`muxing`] module.
//! - The [`UpgradeInfo`], [`InboundUpgrade`] and [`OutboundUpgrade`] traits
//! define how to upgrade each individual substream to use a protocol.
//! See the `upgrade` module.
/// Multi-address re-export.
