Struct Grid 

pub struct Grid<T> { /* private fields */ }

A width × height rectangle of cells, stored row-major. The cell count always equals width * height; deserialising checks it.

Implementations

impl<T> Grid<T>

pub fn from_cells(width: u16, height: u16, cells: Vec<T>) -> Option<Self>

Builds a grid from row-major cells; None if the count is not width * height.

pub fn filled(width: u16, height: u16, value: T) -> Self

where T: Clone,

A width × height grid with every cell set to value.

pub fn width(&self) -> u16

Number of columns.

pub fn height(&self) -> u16

Number of rows.

pub fn cells(&self) -> &[T]

Every cell, row-major.

pub fn in_bounds(&self, pos: Pos) -> bool

Whether pos is inside the grid.

pub fn get(&self, pos: Pos) -> Option<&T>

The cell at pos, or None if out of bounds.

pub fn get_mut(&mut self, pos: Pos) -> Option<&mut T>

The cell at pos for writing, or None if out of bounds.

pub fn neighbors4(&self, pos: Pos) -> impl Iterator<Item = Pos> + '_

The in-bounds neighbours of pos, in Dir::ALL order.

pub fn positions(&self) -> impl Iterator<Item = Pos> + use<T>

Every position, row-major (the order of Grid::cells).

Trait Implementations

impl<T: Clone> Clone for Grid<T>

fn clone(&self) -> Grid<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Grid<T>

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Grid<T>

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl<T> JsonSchema for Grid<T>

where T: JsonSchema,

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.
