Crate libp2p::core

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.

Modules

• connection
• either
• identity
  A node’s network identity keys.
• multiaddr
• muxing
  Muxing is the process of splitting a connection into multiple substreams.
• peer_record
• signed_envelope
• transport
  Connection-oriented communication channels.
• upgrade
  Contains everything related to upgrading a connection or a substream to use a protocol.

Structs

• DecodeError
• Multiaddr
  Representation of a Multiaddr.
• PeerId
  Identifier of a peer of the network.
• PeerRecord
  Represents a peer routing record.
• SignedEnvelope
  A signed envelope contains an arbitrary byte string payload, a signature of the payload, and the public key that can be used to verify the signature.

Enums

• ConnectedPoint
  The endpoint roles associated with an established peer-to-peer connection.
• Endpoint
  The endpoint roles associated with a peer-to-peer communication channel.
• ParseError
• PublicKey
  The public key of a node’s identity keypair.
• UpgradeError
  Error that can happen when upgrading a connection or substream to use a protocol.

Traits

• InboundUpgrade
  Possible upgrade on an inbound connection or substream.
• OutboundUpgrade
  Possible upgrade on an outbound connection or substream.
• ProtocolName
  Types serving as protocol names.
• StreamMuxer
  Provides multiplexing for a connection by allowing users to open substreams.
• Transport
  A transport provides connection-oriented communication between two peers through ordered streams of data (i.e. connections).
• UpgradeInfo
  Common trait for upgrades that can be applied on inbound substreams, outbound substreams, or both.

Functions

• address_translation
  Perform IP address translation.

Type Definitions

• Negotiated
