rustHow to call a closure in RUst


In Rust, a closure can be called by using the call operator, which is written as (). The closure must be assigned to a variable before it can be called. For example, the following code creates a closure and assigns it to the variable my_closure, and then calls it:

let my_closure = || println!("Hello, world!");
my_closure();

The output of this code will be:

Hello, world!

The call operator () is used to call the closure, which will execute the code inside the closure. In this example, the closure prints out the string "Hello, world!".
