Named-Fields §

A struct with components, which can be identified by their name

Tricks §

Supply vaules for new struct: .. EXPR

fn chop(b: Broom) -> (Broom, Broom) {
    let mut broom1 = Broom { height: b.height / 2, .. b };
    let mut broom2 = Broom { name: broom1.name.clone(), .. broom1 };

    broom1.name.push_str(" I");
    broom2.name.push_str(" II");

    (broom1, broom2)
}

Example §

// pub is optional
pub struct GrayscaleMap {
    pub pixels: Vec<u8>,
    pub size: (usize, usize)
}
