Implementations§

Source§

impl<T: Default + Clone> GenericGrid<T>

Source

pub fn new(width: usize, height: usize) -> GenericGrid<T>

Constructs a new two-dimensional GenericGrid<T> of size widthxheight with default values of type T.

Source

pub fn height(&self) -> usize

Returns the width of the grid

Source

pub fn width(&self) -> usize

Returns the height of the grid

Source

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

Returns the element at position (x, y), or None if the position is out of bounds.

Source

pub fn get_unchecked(&self, x: usize, y: usize) -> &T

Returns a pointer to the element at position (x, y), without doing bounds checking.

Source

pub fn set(&mut self, x: usize, y: usize, value: T)

Sets the value of the grid at position (x,y)

Source

pub fn to_vec(self) -> Vec<T>

Converts the GenericGrid<T> to a Vec<T> with indexing grid[x, y] == vec[y*grid.width + x]

Source

pub fn iter(&self) -> GridIter<'_, T>

Returns an iterator over the nodes of the grid. An item of the iterator contains the position and a reference to the node: (x, y, value)

Source

pub fn iter_mut(&mut self) -> GridIterMut<'_, T>

Returns an iterator over the nodes of the grid. An item of the iterator contains the position and a mutable reference to the node: (x, y, value)
