Central repository for work on libp2p

This repository is the central place for Rust development of the libp2p spec.

Warning: While we are trying our best to be compatible with other libp2p implementations, we cannot guarantee that this is the case considering the lack of a precise libp2p specifications.

Repository Structure

The main components of this repository are structured as follows:

• core/: The implementation of mwc-libp2p-core with its Network, Transport and StreamMuxer API on which almost all other crates depend.

• transports/: Implementations of transport protocols (e.g. TCP) and protocol upgrades (e.g. for authenticated encryption, compression, ...) based on the mwc-libp2p-core Transport API .

• muxers/: Implementations of the StreamMuxer interface of mwc-libp2p-core, e.g. (sub)stream multiplexing protocols on top of (typically TCP) connections. Multiplexing protocols are (mandatory) Transport upgrades.

• swarm/: The implementation of mwc-libp2p-swarm building on mwc-libp2p-core with the central interfaces NetworkBehaviour and ProtocolsHandler used to implement application protocols (see protocols/).

• protocols/: Implementations of application protocols based on the mwc-libp2p-swarm APIs.

• misc/: Utility libraries.

• examples/: Worked examples of built-in application protocols (see protocols/) with common Transport configurations.

lib.rs:

Implementation of the libp2p Transport trait for TCP/IP.

Usage

This crate provides a TcpConfig and TokioTcpConfig, depending on the enabled features, which implement the Transport trait for use as a transport with mwc-libp2p-core or mwc-libp2p-swarm.
