Program/Source Code

The source code to create a closure function with parameters is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.

// Rust program to create a closure function 
// with parameter

fn main() {
    let name = "Herry";
    let my_closure = |na| println!("Hello {}", na);
    my_closure(name);
}
