rustHow do I create a variable closure in Rust?

A variable closure in Rust is a closure that captures a variable from its environment. It is created using the move keyword, which captures the variable from its environment and moves it into the closure.

Example code

let x = 5;
let closure = move || x * x;

Output example

closure: [closure@src/main.rs:2:26: 2:35]

Code explanation

• let x = 5;: This declares a variable x with the value 5.
• let closure = move || x * x;: This creates a closure closure that captures the variable x from its environment and moves it into the closure. The closure will return the square of x when called.
