In my limited experience, unfortunately Rust isn't there yet for true "blazingly-fast" low-level code, not without using assembly[1] or linking to external code. For example, there is no (mature) support for SIMD yet. Neither C or C++ has it to be technicall, but at least the compilers do (in the form of intrinsics). But I agree with the overal message, and I'm looking forward to Rust maturing. I think it is the better language although I am no expert at either. [1]: but really, when you start using AVX instructions and the like beyond what the compiler will automate for you, you are just using wrappers around assembly instructions in languages like C today anyway (__mm256_shuffpd, __mm256_perm128f2d)
