How do you create a struct in Rust? Provide a simple example.?

In Rust, a struct is a way to group related data together into a single, custom data type. You can create a struct using the ‘struct‘ keyword followed by the name of the struct and the fields the struct contains.

Here’s a simple example:

    struct Person {
        name: String,
        age: u32,
        is_student: bool,
    }

In this example, we’re defining a ‘Person‘ struct with three fields: ‘name‘ of type ‘String‘, ‘age‘ of type ‘u32‘, and ‘is_student‘ of type ‘bool‘.

To create an instance of this struct, we can use the following syntax:

    let person = Person {
        name: String::from("Alice"),
        age: 25,
        is_student: true,
    };

In this example, we’re creating a new ‘Person‘ instance and assigning it to the ‘person‘ variable. We’re using the curly brace syntax to specify the values for each field. Note that we’re using ‘String::from()‘ to create a new ‘String‘ object for the ‘name‘ field.

We can access fields of the struct using dot notation, like so:

    println!("Name: {}", person.name);
    println!("Age: {}", person.age);
    println!("Is student: {}", person.is_student);

This will output:

    Name: Alice
    Age: 25
    Is student: true

Overall, using structs is a powerful way to organize data and make your code more expressive in Rust.
