Macro coord2d::new_vector

macro_rules! new_vector {
    () => { ... };
    ($start:expr, $end:expr) => { ... };
    ($end:expr) => { ... };
}

creating a new Vector

Example

use coord2d::*;
fn main () {
    let a: coords::Coord = new_coord!(1, 2.0);
    let b: coords::Coord = new_coord!(0.4, 3.3);
    let h:vectors::Vector = new_vector!(a, b);
    println!("{:?}", h);
}

• the var h contains to var start point and end point point
• while magnitude get calculated automatically
