Rust marks five years since its 1.0 release: The long and winding road actually works


Re: On speed

Sounds veeery slow, but in general Rust program speed will be very very close (but slower) than C 1) As there are additional runtime checks that do occur for some operations, 2) precisely because C will let you do weird and wonderful things with your memory etc. A properly written C library will get you there the fastest, but if that doesnt exist and you want to write one, it's probably *safer* in rust.

As you say, the most likely path to success will be changing your algorithm, rather than the same one written in another language. As a mathematician you're probably the most qualified to say, but I'd try to work out if you can get any of your computations done in parallel, then you can use multi threading to physically crank the numbers with less elapsed real world time.
