alt Hacker NewsI would tend to disagree; fundamental to Rust is the concept of zero-cost abstraction. Swift does not do that.
I my view, and I might be wrong, many features of Rust are chosen specifically to have the language comply to the zero-cost rule. Such as the ownership model.
The explicit ownership model in Rust also protects one from the footguns of actors and Tasks in Swift. Rust also makes most mistakes in that area a build time error which is not only a huge time saver but also helps one learn and improve in these areas.
