Struct Manifold 

pub struct Manifold {
    pub normal: Vec2,
    pub rolling_impulse: f32,
    pub points: [ManifoldPoint; 2],
    pub point_count: i32,
}

A contact manifold describes the contact points between colliding shapes. (b2Manifold)

Fields

normal: Vec2

The unit normal vector in world space, points from shape A to body B

rolling_impulse: f32

Angular impulse applied for rolling resistance

points: [ManifoldPoint; 2]

The manifold points, up to two are possible in 2D

point_count: i32

The number of contact points, will be 0, 1, or 2
