Crate wasm_peers

This crate provides an easy-to-use wrapper around WebRTC and DataChannels for a peer to peer connections.

Overview

As creator of agar.io famously stated WebRTC is hard. This library aims to help, by abstracting away all the setup, and providing a simple way to send and receive messages over the data channel.

It’s as easy as providing address to a signaling server instance from accompanying crate and specifying two callbacks. One for when a connection opens, and one for when a message is received. After that you can send messages back and forth without worrying about the implementation details.

Library contains three network , one-to-one, which creates an equal connection between two peers, one-to-many, which specifies a host and arbitrary number of clients and [many-to-many] that creates connection for each pair of peers and allows sending messages to any of them.

Modules

many_to_many

Library module for implementation of the many-to-many topology of peer communication.

one_to_many

Library module for the one-to-many topology in client-server architecture. There can be exactly one instance of MiniServer and arbitrary number of MiniClient’s connected to the same session.

one_to_one

Library module for one-to-one network topology in simple tunnel connection.

Structs

SessionId

Unique identifier of signaling session that each user provides when communicating with the signaling server.

UserId

Unique identifier of each peer connected to signaling server useful when communicating in one-to-many and many-to-many topologies.

Enums

ConnectionType

Specifies what kind of peer connection to create

Functions

get_random_session_id

Returns a new SessionId instance that can be used to identify a session by signaling server.
