How do closures work in Rust?

Closures in Rust are anonymous functions that can capture their environment. They can take parameters and return values.

Can you give me an example of a closure in Rust?

Sure! Here's a simple example:

let add = |a, b| a + b;
let result = add(5, 3);
println!("Result: {}", result);

This closure takes two parameters and returns their sum.

What are the benefits of using closures?

Closures allow for more concise code, enable functional programming patterns, and can capture variables from their surrounding scope.

Are there any performance considerations with closures?

Yes, closures can introduce some overhead, especially if they capture large data structures. It's important to consider their usage in performance-critical code.
