Struct NodeLayout 

#[non_exhaustive]
pub struct NodeLayout {
    pub id: String,
    pub rect: Rect,
    pub rank: usize,
}

Placement of one node: its card rectangle in cells plus its rank.

Engine-produced fact carrier (#[non_exhaustive] per ADR-0003 §1 — cycle 2 will grow it, e.g. with port anchors). Read fields freely; construct through NodeLayout::new (the 0430 editor synthesizes layouts from user drags through the same door).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: String

The node id, echoed from the input.

rect: Rect

Card rectangle in cells; origin-normalized so the layout’s bounding box starts at (0, 0).

rank: usize

Layer index along the flow axis. layered computes it; grid reports the grid row; force computes no hierarchy and honestly reports 0 for every node.

Implementations

impl NodeLayout

pub fn new(id: impl Into<String>, rect: Rect, rank: usize) -> Self
