Does Rust at least make the stronger abstractions as low-cost as they can be with no JIT compiler?

- pron 11y agoOh, it certainly could (I don't know whether it currently does, simply due to compiler maturity), but my "complaint" isn't about Rust's abilities but its use of the term zero cost abstractions.
- steveklabnik 11y agoThe phrase was taken from C++, and refers to the implementation of said abstractions. If you built them yourself, you couldn't have built them better. This still presumes things like an AOT model, but that's what it's meant to call back to, not literally everything in every situation ever.
