Struct CollisionMask 

pub struct CollisionMask {
    pub page: usize,
    pub size: Size,
    pub occupied: Vec<(ElementId, Rect)>,
    pub free: Vec<Rect>,
    pub collisions: Vec<(ElementId, ElementId, Rect)>,
    pub overflow: Vec<ElementId>,
}

JSON-serializable geometry-derived mask.

Fields

page: usize

Page index.

size: Size

Page size.

occupied: Vec<(ElementId, Rect)>

Selected occupied rectangles.

free: Vec<Rect>

Disjoint free rectangles.

collisions: Vec<(ElementId, ElementId, Rect)>

Pairwise collisions.

overflow: Vec<ElementId>

Visual overflow IDs.

Implementations

impl CollisionMask

pub fn derive( scene: &ResolvedScene, page: usize, view: MaskView, ) -> Result<Self>

Derives a mask from resolved geometry; bitmap pixels are never queried.

pub fn derive_bounded( scene: &ResolvedScene, page: usize, view: MaskView, limits: &ResourceLimits, ) -> Result<Self>

Derives a mask under the caller’s scene and diagnostic geometry budgets.

pub fn to_json(&self) -> Result<Vec<u8>>

Serializes stable geometry JSON.

pub fn to_json_bounded(&self, limits: &ResourceLimits) -> Result<Vec<u8>>

Serializes stable geometry JSON under caller-supplied budgets.
