Why doesn't Collision implement Copy or Clone?

I recently made a simple 2D game with basic collision detection using bevy::sprite::collide_aabb::Collision. I wanted to send Collisions as events so that downstream systems could react to the collision direction.

I quickly found that because it doesn't implement Copy or Clone, my only options were to either do everything I needed to do with the Collision before moving it into the EventWriter, or do an unsafe bitwise copy.

Collision seems like a very basic enum. Why doesn't it derive these traits?

This should impl both: can you make a PR?
