Enum and Constant of Rust

⚡ use - defined to import some or all enum defined and used them directly.

⚡ const - keyword that allowed you to define an unchangeable value.

#[derive(Debug)]
enum Rustlearning{
    HOME,
    STUDENT,
}

fn main(){

    use crate::Rustlearning::*;
    
    let status = HOME;
    println!("{:#?}", status);

}
