Struct Bound 

pub struct Bound<'m> { /* private fields */ }

A boundary loop of a Face (FACE_BOUND / FACE_OUTER_BOUND).

Implementations

impl<'m> Bound<'m>

pub fn is_outer(&self) -> bool

true for FACE_OUTER_BOUND.

pub fn key(&self) -> EntityKey

This bound’s global identity (a Copy key for maps / deduplication).

pub fn orientation(&self) -> bool

Whether this loop runs in its stated sense with respect to the face — the FACE_BOUND orientation flag; false means the loop is used reversed. One of the three orientation layers a kernel composes: Face::same_sense (surface normal), this flag (whole loop), and the per-edge flag of Bound::oriented_edges.

pub fn edges(&self) -> impl Iterator<Item = Edge<'m>> + 'm

Edges of this boundary loop (only EDGE_LOOP loops carry edges), without their per-edge orientation — use Bound::oriented_edges to assemble a wire.

pub fn oriented_edges(&self) -> impl Iterator<Item = (Edge<'m>, bool)> + 'm

Edges of this boundary loop with each ORIENTED_EDGE’s orientation: true means the edge is traversed in its own start → end direction at this position in the loop, false reversed — what a kernel needs to assemble the loop into a wire without end-matching heuristics.

Trait Implementations

impl<'m> Clone for Bound<'m>

fn clone(&self) -> Bound<'m>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
