I think you can in rust as long as args is a slice. Rust doesn't have varargs except for c interop. A slice or Vec of function pointers is the idiomatic way to do the same thing. Something like: fn compose<X, T>(start: Box<Fn(T) -> X>, args: Vec<Box<Fn(T) -> T>>) -> Fn(T) -> X { move |x: X| { let mut x = x; for func in args.iter(). reversed() { x = func(x); } start(x) } }
