[P1R]

Description

Solves issue #5554 also referenced first in #4449

Notes & open questions

Differences between the ping example and the ping tutorial

Cargo.toml

• libp2p missing features from tutorial in the example: "tls", "dns" "websocket", and "macros".
• using latest version of the dependencies .

src/main.rs

• SwarmBuilder tcp config does not implement tcp but noise instead.
• Ping timeout in the tutorial is 30 seconds while in the example is Duration::from_secs(u64::MAX).

Procedure

• Reviewed tutorial procedures can be verified here
• Tutorial is located at the following path: libp2p/src/tutorials/ping.rs
• It builds when located at libp2p using the following command: cargo doc --open

Conclusion: Followed the example code for the new tutorial version to standardize.

Change checklist

• I have performed a self-review of my own code
• I have made corresponding changes to the documentation
• I have added tests that prove my fix is effective or that my feature works
• A changelog entry has been made in the appropriate crates

LGTM Thanks! Btw you mentioned that in the tutorial the timeout is 30 seconds but it's in both u64::MAX

Yes, my error. When I was doing the review /verification of the tutorial steps, I got an incorrect version. I was following this one: https://docs.rs/libp2p/0.53.2/libp2p/tutorials/ping/index.html. But after I did follow up on building and verifying with the cargo doc --open
