How to create a function with variable number of arguments in Rust?

Hello everyone! I just started learning Rust after C++ and Python, and I ran into a problem. In C++ I can write a function with variable number of arguments using `...` (variadic templates), and in Python — using `*args`. For example, I want to create a `sum_all` function that adds any number of integers: ```rust // How do I do this in Rust? fn sum_all(...) -> i32 { // something here } fn main() { println!("{}", sum_all(1, 2, 3)); // 6 println!("{}", sum_all(10, 20, 30, 40)); // 100 } ``` I've read that Rust doesn't support classic variadic functions like in C. But there are macros? Or can I use slices? I tried passing a vector, but it's inconvenient — I have to create `vec!` every time. Is there an idiomatic way to do this in Rust? I need exactly a re
