Rust - Crates - Public

The keyword pub makes something public, like a function, module, enum, struct etc.

However, structs are special. pub in front of them just makes them public, not the members inside. The members will not be read nor writable. To make them read/writable, add the pub keyword to the variable itself.

Example:

mod house {
    pub struct Kitchen {
        pub plates: i32,
        sinks: i8,
    }

    impl Kitchen {
        pub fn duel_sink(num_plates: i32) -> Kitchen {
            Kitchen {
                plates: num_plates,
                sinks: 2,
            }
        }
    }
}

pub fn build_home() {
    let mut home = house::Kitchen::duel_sink(8);
    home.plates += 1;

    // Cannot read nor write to private struct field
    //home.sinks += 1;
    //println!("Num sinks: {}", home.sinks);
}
