We use rust for everything at MobileCoin. I like to think of the compiler as fussy, but when you make the compiler happy your code just works. No buffer overflows as long as you don’t use unsafe code, multi-threading by default. The audits on our code have basically only turned up logic errors and out of date crates (yes it’s always possible stuff was missed, but it feels a lot different than the C/++ and functional audits I’ve been involved with in the past).

We love it and wouldn’t trade it for a different language at this point.

P.S. we’re hiring remote and sf Bay Area. If you are interested in working on digital cash for use in messaging applications, drop me at line!
