I just tried this:

https://github.com/search?q=lang%3Arust&type=repositories&s=...

Filter by language to rust and then select sort by most stars, and the top repository has 249 stars...

Though if I add a filter for stars greater than 1000 the results look way better:

https://github.com/search?q=lang%3Arust+stars%3A%3E1000&type...
