Struct Layout 

pub struct Layout {
    pub vertices: Vec<LayoutVertex>,
    pub edges: Vec<LayoutEdge>,
    pub faces: Vec<LayoutFace>,
    pub changed: BTreeSet<String>,
    pub corners: Vec<[usize; 4]>,
}

A sheet laid out flat (see the module docs). Edges and vertices a cut took away stay in the lists, used by no face.

Fields

vertices: Vec<LayoutVertex>

edges: Vec<LayoutEdge>

faces: Vec<LayoutFace>

changed: BTreeSet<String>

The keys of the sheet’s edges a cut split or took away.

corners: Vec<[usize; 4]>

Per bend, the vertices at its corners as built — where its parent edge starts and ends, where its child edge ends and starts — which stay in the list when a cut takes them away.

Implementations

impl Layout

pub fn used_edges(&self) -> Vec<usize>

The edges some face uses, in order.

pub fn subtract(&mut self, cut: &[Vec<CutCurve>]) -> GeopResult<()>

Takes the area inside cut — closed loops, counter-clockwise, apart from each other — out of the faces: their edges inside it go, the cut’s curves inside a face become its edges, every curve split where they cross, or where a joint of the cut lies on one. Refuses, naming the curves, a cut that crosses an edge at its end, touches one, runs along one, or crosses one that is no line or arc; and one that splits a face in two, takes one away entirely, or misses the sheet.

Trait Implementations

impl Clone for Layout

fn clone(&self) -> Layout

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Layout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Layout

fn default() -> Layout

Returns the “default value” for a type.
