Frankly, I do most of my searching these days directly on https://std.rs and https://docs.rs . But yeah, those are usually better as a reference than for learning.

You can look through https://lib.rs and https://awesome-rust.com , if you’re searching for a specific library.

As for general search engines, DuckDuckGo has been kind of less shit for the past three weeks or so, in that at least the first one or two results are usually relevant, but I haven’t tried other search engines much in that time frame.

Another tip is to make use Clippy. Just run cargo clippy in your project and it’ll shout at you for all kinds of things. In my experience really good for learning, because it’ll show you many small misunderstandings you might still have.
