Enum LatticeKind 

#[non_exhaustive]
pub enum LatticeKind {
    Square,
    Hex,
}

Supported lattice families.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Square

Orthogonal square lattice.

Hex

Axial-coordinate hexagonal lattice.

Implementations

impl LatticeKind

pub fn model_point(self, coord: Coord) -> Point2<f32>

Map an integer lattice coordinate into the model plane.

Square coordinates map to (u, v). Hex axial coordinates map to (q + 0.5*r, sqrt(3)/2*r), using unit nearest-neighbour spacing in the model plane.

This dispatches to the Lattice::model_point of the family impl, so callers holding only a LatticeKind need not name the concrete family type.

pub fn neighbour_offsets(self) -> &'static [Coord]

Cardinal neighbour offsets for this family (4 for square, 6 for hex).

pub fn symmetry_transforms(self) -> &'static [GridTransform]

The coordinate symmetry group for this family (D4 for square, D6 for hex).

pub fn axis_family_count(self) -> usize

Number of distinct axis families: 2 for square (±u, ±v), 3 for hex (the three axial directions). This is the k the topological classifier matches each edge against.

pub fn model_axis_directions(self) -> &'static [Vector2<f32>]

Unit model-plane directions of the k primitive axis families.

Returns one direction per family (axis_family_count() of them), each a unit vector in the model plane. For square these are (1,0) and (0,1); for hex they are the three axial step directions folded into the upper half-plane. The topological pipeline uses these as the canonical orientation targets when synthesizing per-corner axes.

pub fn cell_topology(self) -> CellTopology

How Delaunay triangles map to lattice cells for this family.
