Currently the icon for Rust Lang is empty. I understand that Rust is not very big right now to receive a lot of attention, but I believe setting a default icon is not a big deal. I mean, look at Go, the default icon for Go projects is the mascot Gopher, and the crab of Rust Lang can be just as cute.

All in all, please consider setting the default icon for Rust as it mascot, like Go. Should not be that hard anyway. Thank you.
