Function ncollide2d::query::contact

pub fn contact<N: RealField>(
    m1: &Isometry<N>, 
    g1: &dyn Shape<N>, 
    m2: &Isometry<N>, 
    g2: &dyn Shape<N>, 
    prediction: N
) -> Option<Contact<N>>

Computes one contact point between two shapes.

Returns None if the objects are separated by a distance greater than prediction.
