rustRust lang class property

Class properties in Rust are defined using the pub keyword. This keyword makes the property accessible from outside the class. The syntax for defining a class property is as follows:

pub property_name: type

For example, if we want to define a class property called name of type String, we can do so as follows:

pub name: String

The following is an example of a class with a property called name of type String:

pub struct Person {
    pub name: String,
}

fn main() {
    let person = Person {
        name: String::from("John"),
    };

    println!("Name: {}", person.name);
}

Output

Name: John

Explanation:

• pub: This keyword makes the property accessible from outside the class.
• name: This is the name of the property.
• String: This is the type of the property.
• Person: This is the name of the class.
• let person = Person { name: String::from("John") };: This line creates an instance of the Person class and sets the name property to John.
• println!("Name: {}", person.name);: This line prints the value of the name property.
