Struct Edges 

pub struct Edges { /* private fields */ }

Implementations

impl Edges

pub fn empty() -> Self

pub fn from_edges<I: IntoIterator<Item = Edge>>(it: I) -> Self

pub fn from_polygon(p: &Polygon) -> Self

Edges of a single polygon — the hull plus every hole boundary, in traversal order.

pub fn from_region(r: &Region) -> Self

Edges of every polygon in a region.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn edges(&self) -> &[Edge]

pub fn into_inner(self) -> Vec<Edge>

pub fn centers(&self, length: i64) -> Edges

Replace each edge with a length-long segment centered at its midpoint, oriented along the source edge. Edges shorter than length are emitted unchanged.

pub fn extended(&self, before: i64, after: i64) -> Edges

Extend each edge by before along the −direction at a and by after along the +direction at b. Useful for converting an edge to a “ray” with finite extent.

pub fn with_angle(&self, angle_deg: f64, tolerance_deg: f64) -> Edges

Filter edges whose angle (mod 180°) is within tolerance_deg of angle_deg.

pub fn not_with_angle(&self, angle_deg: f64, tolerance_deg: f64) -> Edges

pub fn length_at_least(&self, min: i64) -> Edges

pub fn length_at_most(&self, max: i64) -> Edges

pub fn interacting(&self, other: &Edges) -> Edges

Keep edges whose bbox overlaps any edge in other. v1 uses bbox intersection — sufficient for axis-aligned edge interaction (where touching edges share a bbox boundary point).

pub fn outside_part(&self, region: &Region) -> Edges

Keep the parts of each edge that lie strictly outside region. Implemented for axis-aligned edges over axis-aligned regions — non-axis-aligned edges are returned unchanged.

pub fn inside_part(&self, region: &Region) -> Edges

Keep the parts of each edge that lie inside region.

Trait Implementations

impl Clone for Edges

fn clone(&self) -> Edges

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Edges

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

Formats the value using the given formatter.

impl Default for Edges

fn default() -> Edges

Returns the “default value” for a type.
