Struct ContactKey 

pub struct ContactKey {
    pub body_i: usize,
    pub body_j: usize,
    pub cell: [i64; 3],
}

A stable identifier for a contact across timesteps.

Ordered so that the pair (i, j) and (j, i) cannot collide, and so the quantized point is read in the frame named by reference.

Fields

body_i: usize

The lower-numbered body of the pair (Collision::WORLD = world).

body_j: usize

The higher-numbered body of the pair (Collision::WORLD = world).

cell: [i64; 3]

Contact point in body_i’s local frame, quantized to the cache’s grid.
