How do you find non-top-level packages in nixpkgs? (beehaw.org)

This is something that I struggle with. I know how to find top-level packages like git or cowsay. But what about utilities under nested paths? I always spend ages digging through the nixpkgs source code to try to find utilities to use in my nix expressions.

Today I want to use buildRustPackage. It's defined here, and is propagated here. But how do I access it given a pkgs variable? I have no idea!

https://search.nixos.org/packages is no help

nix search nixpkgs doesn't find it

I think I need to search by attribute name, not by derivation name. But I don't know how to do that.

There was a talk about that problem at this years NixCon, maybe it'll give you some ideas.
