Struct NavmeshCell 

pub struct NavmeshCell { /* private fields */ }

One convex walkable polygon in a navmesh, keyed by a stable cell_id.

Cell ids are the durable identity used by dynamic availability updates; portal endpoints must lie on the cell boundary. Construction does not validate—call Self::validate (or Navmesh::validate) before search.

Implementations

impl NavmeshCell

pub fn new(cell_id: impl Into<String>, vertices: Vec<Point2>) -> NavmeshCell

Creates an unvalidated cell; geometry and id contracts are checked by Self::validate.

pub fn cell_id(&self) -> &str

Stable string identity for this cell within a mesh.

pub fn vertices(&self) -> &[Point2]

Convex polygon ring in world coordinates (CCW or CW; validation checks area).

pub fn validate(&self) -> Result<(), NavmeshValidationError>

Checks non-empty id, at least three vertices, non-zero area, and convexity.

Errors

Returns NavmeshValidationError when the cell id or polygon geometry violates the navmesh contract.

pub fn contains_point_inclusive(&self, point: Point2) -> bool

Inclusive membership: interior points and boundary edges (including vertices) count.

pub fn has_boundary_segment(&self, start: Point2, end: Point2) -> bool

Whether both endpoints of a portal segment lie on a single cell boundary edge.
