Struct Grid2 

pub struct Grid2<T> { /* private fields */ }

A row-major grid with fixed-width dimensions.

Implementations

impl<T> Grid2<T>

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

Constructs a grid when cells exactly matches its checked dimensions.

pub const fn width(&self) -> u16

Returns the grid width.

pub const fn height(&self) -> u16

Returns the grid height.

pub fn get(&self, x: u16, y: u16) -> Option<&T>

Returns a cell by coordinate.

pub fn get_mut(&mut self, x: u16, y: u16) -> Option<&mut T>

Returns a mutable cell by coordinate.

pub fn row(&self, y: u16) -> Option<&[T]>

Returns one row as a contiguous slice.

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

Returns all cells in deterministic row-major order.

impl<T: Clone> Grid2<T>

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

Constructs a grid filled with clones of value, or GridError::TooLarge when its cells cannot be allocated.
