Rust Function Overloading – Call for Experimentation

// This program demonstrates the current stable way to call an overloaded
// function that expects a tuple of arguments. The nightly `splat` feature
// is not available in Rust 1.98.1, so we use the tuple syntax instead.
fn hypot(args: (f64, f64, f64)) -> f64 {
    // In a real FFI scenario this would call into C++.
    // Here we just compute the Euclidean norm.
    let (x, y, z) = args;
    (x * x + y * y + z * z).sqrt()
}

fn main() {
    // Call with a tuple: (2.0, 3.0, 6.0)
    let result = hypot((2.0, 3.0, 6.0));
    println!("hypot(2.0, 3.0, 6.0) = {}", result);
}
