I’ve used Ada. I’ve not used Rust beyond a few hello world type programs. Personally, I like Ada quite a bit, and I really do like Spark. But I think that Ada and Rust are aiming at similar problems in entirely different ways. One of the key design choices in Ada was to emphasize maintainability. Rust’s answer was to emphasize memory safety. While the Ada compiler does quite a few safety checks, these aren’t part of the spec so that will vary by compiler. I am not sure that direct comparisons between the two languages are entirely useful. Ada is used for things like cruise missiles and jets. Rust is used for things like browsers and reimplementing GNU. Both are important, but they aren’t exactly similar.
