# Objective
To implement fmt::Display for the direction types. The reason that this
would be a good addition is that I often find myself using println! to
debug things with directions and adding the extra ":?" was getting a
little annoying. It would also be better for any potential CLI apps that
might need to output a direction.
## Solution
Copied glam's implementation of Display for each length of direction.
I.E Vec3's display for Dir3.
## Testing
- Did you test these changes? If so, how?
Yes, I wrote a little script that printed out the different directions
and compared it to their vector counterparts.
Here it is if anyone's interested
```
use bevy_math::*;
fn main() {
let dir2 = Dir2::from_xy(0.0, 1.0).unwrap();
let dir3 = Dir3::from_xyz(0.0, 1.0, 0.0).unwrap();
let dir3a = Dir3A::from_xyz(0.0, 1.0, 0.0).unwrap();
let dir4 = Dir4::from_xyzw(0.0, 1.0, 0.0, 0.0).unwrap();
let vec2 = Vec2::new(0.0, 1.0);
let vec3 = Vec3::new(0.0, 1.0, 0.0);
let vec4 = Vec4::new(0.0, 1.0, 0.0, 1.0);
println!("{dir2} {dir3} {dir3a} {dir4}");
println!("{vec2}, {vec3}, {vec4}")
}
```
- Are there any parts that need more testing?
Perhaps
