Struct FixedPolygon 

pub struct FixedPolygon<const N: usize> { /* private fields */ }

A polygon with a statically-allocated vertex array of capacity N.

Vertices are stored inline; no heap allocation is performed.

Implementations

impl<const N: usize> FixedPolygon<N>

pub fn new() -> Self

Creates an empty FixedPolygon.

pub fn try_push(&mut self, p: Point2D) -> bool

Attempts to push a vertex. Returns false if the polygon is full.

pub fn len(&self) -> usize

Returns the number of vertices.

pub fn is_empty(&self) -> bool

Returns true if the polygon has no vertices.

pub fn vertices(&self) -> &[Point2D]

Returns a slice of the current vertices.

pub fn signed_area(&self) -> f64

Computes the signed shoelace area (positive for CCW).

pub fn area(&self) -> f64

Computes the absolute area using the shoelace formula.

pub fn perimeter(&self) -> f64

Computes the perimeter (sum of edge lengths).

pub fn bbox(&self) -> Option<BBox2D>

Returns the axis-aligned bounding box, or None if the polygon is empty.

pub fn centroid(&self) -> Option<Point2D>

Computes the centroid, or None if the polygon is empty.

Trait Implementations

impl<const N: usize> Default for FixedPolygon<N>

fn default() -> Self

Returns the “default value” for a type.
