What are advanced closures in Rust?

Advanced closures in Rust are functions that can capture variables from their environment, allowing for more flexible and powerful programming patterns.

Can you give me an example of a closure that captures variables?

Sure! Here's a simple example:

let x = 10;
let add_x = |y| y + x;
println!("Result: {}", add_x(5)); // Outputs: Result: 15

What are the differences between closures and regular functions?

Closures can capture their environment, while regular functions cannot. Closures are also more flexible in terms of types and can be used as arguments to other functions.

How do I specify the types of parameters in a closure?

You can specify types in a closure by declaring them explicitly, like this:

let multiply = |x: i32, y: i32| x * y;
