use - Rust By Example
Description: A description

# use

The `use` declaration can be used so manual scoping isn't needed:

    // An attribute to hide warnings for unused code.
    #![allow(dead_code)]

    enum Status {
        Rich,
        Poor,
    }

    enum Work {
        Civilian,
        Soldier,
    }

    fn main() {
        // Explicitly `use` each name so they are available without
        // manual scoping.
        use crate::Status::{Poor, Rich};
        // Automatically `use` each name inside `Work`.
        use crate::Work::*;

        // Equivalent to `Status::Poor`.
        let status = Poor;
        // Equivalent to `Work::Civilian`.
        let work = Civilian;

        match status {
            // Note the lack of scoping because of the explicit `use` above.
            Rich => println!("The rich have lots of money!"),
            Poor => println!("The poor have no money..."),
        }

        match work {
            // Note again the lack of scoping.
            Civilian => println!("Civilians work!"),
            Soldier  => println!("Soldiers fight!"),
        }
    }
