Why the changing from rust,ignore to text?

I do not want to compile that piece of code, and I do not want to have an "ignore" test in the output like this:

& cargo test --doc
test src/tracker/mod.rs - tracker (line 83) - compile ... ignore

Sometimes the necessary setup to compile is too verbose for the documentation. For example:

let announce_data = tracker.announce(&info_hash, &mut peer, &peer_ip).await;

That line would require building a tracker, a peer, etc.

We have the tests if you want to check a fully operational example; maybe I could add a link to the tests in these cases.

I can also implement the full working example and hide the lines that are not interesting for the documentation.

The link to how to hide code in docs is wrong. I've read somewhere else that you can do that, but I do not find it.

The link was not wrong it's only that you need to prepend the hashtag to all the lines you want to hide:

//! ```rust,no_run
//! # use torrust_tracker::tracker::peer;
//! # use torrust_tracker::shared::bit_torrent::info_hash::InfoHash;
//! # // ...
//! 
//! let announce_data = tracker.announce(&info_hash, &mut peer, &peer_ip).await;
//! ```

That would show only:

let announce_data = tracker.announce(&info_hash, &mut peer, &peer_ip).await;
