Are you talking about the memory management model or the syntax. For the syntax, it's a matter of getting used to. For memory management, Rust has alloc::rc, so Rust gives you Swift + more options. Swift is backed by Apple, but whether they are willing to invest in a Swift WASM platform is another deal. The bull case for Rust is getting capital (whether money or dev time) from Microsoft and Facebook as both these companies don't have an equivalent and have use cases for Rust.
