It isn’t, if you’re already familiar with Rust. That’s all I’m saying. Swift usage is largely isolated to Apple’s ecosystem, which doesn’t have a ton of overlap with the open-source ecosystem.

And I actually disagree that Rust is overhyped, because it can be used for creating libraries which can be called from virtually any other language, like you can with C and C++. Which means you’re not locked into the Rust/Apple/whatever ecosystem, but instead could be coding the next SQLite without needing to be fluent in footgun.

From what I can tell, this would theoretically be possible in Swift, but hasn’t been implemented: https://forums.swift.org/t/formalizing-cdecl/40677

But even if Rust was the most overhyped garbage, it would still be garbage that people are familiar with. ¯\_(ツ)_/¯
