Struct b2Manifold 

#[repr(C)]
pub struct b2Manifold {
    pub normal: b2Vec2,
    pub rollingImpulse: f32,
    pub points: [b2ManifoldPoint; 2],
    pub pointCount: c_int,
}

A contact manifold describes the contact points between colliding shapes. @note Box2D uses speculative collision so some contact points may be separated.

Fields

normal: b2Vec2

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

rollingImpulse: f32

Angular impulse applied for rolling resistance. N * m * s = kg * m^2 / s

points: [b2ManifoldPoint; 2]

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

pointCount: c_int

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