Swift's type checker works quite differently than Rust's. I'm not aware of any exponential time complexity issues in type-checking Rust code.

Exponential performance cliff compiling associated types with equality constraints[1]. It was first opened in 2015 and was only recently addressed. Rust certainly has the potential for exponential times when performing large inference.
