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

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.

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

Executor

Implemented on objects that can run a Future in the background.

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.
