Whenever I encounter an interesting Rust programming technique, I add it to this blog post. I've amassed a bit of a collection. Hopefully someone finds it interesting and useful!
Nice job! I’d add that the target of the Rustdoc link shortcuts can be customized, in case they are not autodetected or point to an undesired location, like so:
/// Use a [Tool]
///
/// [Tool]: lib::types::Tool
That will make the word Tool point to that type (note that the namespaces there - in lib::types::Tool - are relative to the current module / context, so you can use an imported name directly there too, for example).
