Function node_ring_cubic 

Source 
pub fn node_ring_cubic(
    source: (i32, i32, i32),
    radius: i32,
) -> Vec<(i32, i32, i32)>
Expand description

Finds the nodes on a ring around a given source point in a Cubic coordinate system. source is of the form (x, y, z). radius is the particular ring you want to know the nodes of.

For instance radius = 2 for the second ring around the origin:
