Cool - congrats! Would love to hear more about why you chose Rust for this?

  Thank you! We chose Rust for a few main reasons: - It's an ideal language for writing security-focused software given that it eliminates memory safety bugs (a leading cause of security vulnerabilities in the wild). - Authorization is generally on the critical path, so providing a decision quickly is very important. Rust is extremely fast, but more crucially it doesn't have runtime garbage collection so there's no possibility of an ill-timed GC run disrupting your application. - Rust has a great language interoperability story. We designed oso as a library that you embed in your application. The upshot of that is that we've already built Java, Python, and Ruby libraries, with additional languages to follow. Using Rust allowed us to write the core logic and runtime once in a correct, extremely performant language and then write the language libraries as thin shells around the Rust core. That lowered the bar for expanding oso to new languages pretty dramatically.
