Trait for implementing a Grid in three dimensions

Required Methods

fn dimensions(&self) -> Point3D

The dimensions of the Grid. The only method that must be defined.

Provided Methods

fn lower_bound(&self) -> Point3D

The lower bound. Defaults to (0, 0, 0).

fn upper_bound(&self) -> Point3D

The upper bound. Defaults to the dimensions itself.

fn in_bounds(&self, point: Point3D) -> bool

Check if a point is in the bounds of the grid.

fn point3d_to_index(&self, point: Point3D) -> usize

Convert a point to an index.

Useful if you store the grid in a one-dimensional array.

fn index_to_point3d(&self, index: usize) -> Point3D

Convert an index to a point.

Useful if you store the grid in a one-dimensional array.

fn is_opaque(&self, point: Point3D) -> bool

Check if a point is traversable.

Defaults to always, so you may want to implement this.

fn get_possible_neighbors(&self, point: Point3D) -> [Point3D; 26]

Get all possible neighbors of the point, regardless if the point or its neighbors is in bounds, opaque, or neither.

fn is_possible_neighbor(&self, p1: Point3D, p2: Point3D) -> bool

Check if two points are possible neighbors.

Does not check if either points are inbounds or non-opaque.

fn get_neighbors(&self, point: Point3D) -> [Option<Point3D>; 26]

Get the neighbors that is in bounds and not opaque.

fn is_neighbor(&self, p1: Point3D, p2: Point3D) -> bool

Check if two points are neighbors.

Checks if either points are inbounds or non-opaque.

fn get_neighbors_with_cost( &self, point: Point3D, ) -> [(Option<Point3D>, BigRational); 26]

Get the neighbors with the associated cost.

Defaults to all eight neighbors having a cost of 1.0 if the neighbor is valid.

If you want the diagonals to cost sqrt(2), reimplement this method yourself.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
