Starting with nightly-2023-09-10, the `[lints]` section in `Cargo.toml` files is stable. Together with workspace inheritance, this can be used to declare all lints we want to enforce in a single place. Resolves: #4484. Pull-Request: #4575.
Description
The ping example showcases how to create a network of nodes that establish connections, negotiate the ping protocol, and ping each other.
Usage
To run the example, follow these steps:
-
In a first terminal window, run the following command:
cargo runThis command starts a node and prints the
PeerIdand the listening addresses, such asListening on "/ip4/0.0.0.0/tcp/24915". -
In a second terminal window, start a new instance of the example with the following command:
cargo run -- /ip4/127.0.0.1/tcp/24915Replace
/ip4/127.0.0.1/tcp/24915with the listen address of the first node obtained from the first terminal window. -
The two nodes will establish a connection, negotiate the ping protocol, and begin pinging each other.
Conclusion
The ping example demonstrates the basic usage of libp2p to create a simple p2p network and implement a ping protocol. By running multiple nodes and observing the ping behavior, users can gain insights into how libp2p facilitates communication and interaction between peers.
