Example of struct public field in Rust

// plain

A struct public field in Rust is a field of a struct that is accessible outside of the struct. This allows the struct to be used in a variety of ways, such as passing data between functions or creating a public API.

Example code

struct MyStruct {
    pub field: i32,
}

fn main() {
    let my_struct = MyStruct { field: 5 };
    println!("{}", my_struct.field);
}

Output example

5

Code explanation

• struct MyStruct {: This line declares a new struct called MyStruct.
• pub field: i32,: This line declares a public field called field of type i32.
• let my_struct = MyStruct { field: 5 };: This line creates a new instance of MyStruct and assigns the value 5 to the field field.
• println!("{}", my_struct.field);: This line prints the value of the field field of the my_struct instance.
