What are structs and methods in Rust?

What are structs in Rust?

Structs in Rust are custom data types that let you package related data together. They are similar to classes in other languages.

How do I define a method for a struct?

You define a method for a struct using the impl keyword followed by the struct name. For example: impl MyStruct { fn my_method(&self) { ... } }.

Can you give me an example of a struct with methods?

Sure! Here's a simple example:

struct Rectangle {
    width: u32,
    height: u32,
}

impl Rectangle {
    fn area(&self) -> u32 {
        self.width * self.height
    }
}

This defines a Rectangle struct with a method to calculate its area.

What are the benefits of using structs in Rust?

Structs help organize related data and provide a clear structure for your code, making it easier to manage and understand.
