Previously, a connection would be shut down immediately as soon as its `ConnectionHandler` reports `KeepAlive::No`. As we have gained experience with libp2p, it turned out that this isn't ideal. For one, tests often need to keep connections alive longer than the configured protocols require. Plus, some usecases require connections to be kept alive in general. Both of these needs are currently served by the `keep_alive::Behaviour`. That one does essentially nothing other than statically returning `KeepAlive::Yes` from its `ConnectionHandler`. It makes much more sense to deprecate `keep_alive::Behaviour` and instead allow users to globally configure an `idle_conncetion_timeout` on the `Swarm`. This timeout comes into effect once a `ConnectionHandler` reports `KeepAlive::No`. To start with, this timeout is 0. Together with https://github.com/libp2p/rust-libp2p/issues/3844, this will allow us to move towards a much more aggressive closing of idle connections, together with a more ergonomic way of opting out of this behaviour. Fixes #4121. Pull-Request: #4161.
Examples
A set of examples showcasing how to use rust-libp2p.
Getting started
Individual libp2p features
-
Chat A basic chat application demonstrating libp2p and the mDNS and Gossipsub protocols.
-
Distributed key-value store A basic key value store demonstrating libp2p and the mDNS and Kademlia protocol.
-
File sharing application Basic file sharing application with peers either providing or locating and getting files by name.
While obviously showcasing how to build a basic file sharing application with the Kademlia and Request-Response protocol, the actual goal of this example is to show how to integrate rust-libp2p into a larger application.
-
IPFS Kademlia Demonstrates how to perform Kademlia queries on the IPFS network.
-
IPFS Private Implementation using the gossipsub, ping and identify protocols to implement the ipfs private swarms feature.
-
Ping Small
ping
clone, sending a ping to a peer, expecting a pong as a response. See tutorial for a step-by-step guide building the example. -
Rendezvous Rendezvous Protocol. See specs.
