Function compute_relative 

pub fn compute_relative(
    nodes: &[(u32, (f32, f32))],
    edges: &[(u32, u32)],
    gap: f32,
) -> RelativeLayout

Lay out sized nodes and route their edges with layout-rs.

Regions are opaque rectangles; callers size their contents bottom-up. Node ids must be unique, sizes and gap finite, and all endpoints present. Compute once per graph edit, rather than per frame.

Panics

Panics if an edge refers to an absent node.
