Function ncollide::query::proximity

pub fn proximity<P, M>(
    m1: &M, 
    g1: &(Shape<P, M> + 'static), 
    m2: &M, 
    g2: &(Shape<P, M> + 'static), 
    margin: <P as EuclideanSpace>::Real
) -> Proximity where
    M: Isometry<P>,
    P: Point, 

Tests whether two shapes are in intersecting or separated by a distance smaller than margin.
