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!
In tip #3 I don't see any benefit of doing impl AsRef<[T]> over &[T]
@calcopiritus @hatchet That way you can pass a reference or anything that can be turned into a reference as an argument. So the caller can supply a &T, Box, Rc, Arc, … (I dont’t know if there is a blanket impl so that even T itself will work.
Well, actually I would tend to agree that &[T] is preferable to AsRef in most cases; all of the smart pointers you mentioned can also easily be turned into plain references. I probably could have chosen a better example.
Bookmarked :)
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).

These are actually nice, thanks!
