rustRust struct with all public fields

A Rust struct with all public fields is a struct that has all of its fields declared as public. This means that any code outside of the struct can access and modify the fields.

Example code

struct MyStruct {
    pub field1: i32,
    pub field2: String,
}

fn main() {
    let mut my_struct = MyStruct {
        field1: 10,
        field2: String::from("Hello"),
    };

    my_struct.field1 = 20;
    println!("field1 = {}", my_struct.field1);
}

Output example

field1 = 20

Code explanation

• struct MyStruct {: This is the start of the struct definition.
• pub field1: i32,: This declares a public field named field1 of type i32.
• pub field2: String,: This declares a public field named field2 of type String.
• let mut my_struct = MyStruct {: This creates a mutable instance of the MyStruct struct.
• my_struct.field1 = 20;: This assigns the value 20 to the field1 field of the my_struct instance.
• println!("field1 = {}", my_struct.field1);: This prints the value of the field1 field of the my_struct instance.
