Struct endlessgrid::Grid

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

An endless 2D grid of type T implemented using chunks

Implementations

impl<T: Clone> Grid<T>

pub fn len(&self) -> usize

Gets length of the grid, aka. how many cells there are

pub fn get(&self, index: impl Into<(i32, i32)>) -> Option<&T>

Gets a immutable reference to T

pub fn get_mut(&mut self, index: impl Into<(i32, i32)>) -> Option<&mut T>

Gets an mutable reference to T

pub fn insert(&mut self, index: impl Into<(i32, i32)>, t: T)

Insert T

pub fn astar<F: Fn(AStarVisit<'_, T>) -> bool>( &self, start: impl Into<(i32, i32)>, end: impl Into<(i32, i32)>, visit: F ) -> Option<Vec<(i32, i32)>>

Perform the A-star algorithm F is a function which returns falsewhen path is blocked andtrue` when not blocked

pub fn cast_ray<F: FnMut(RayVisit<'_, T>) -> bool>( &self, start: impl Into<(f32, f32)>, end: impl Into<(f32, f32)>, f: F )

Casts a ray from start to end and call a function F for each cell visited

The ray will be traced until F returns false or untill end has been reached

Trait Implementations

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

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

Returns a copy of the value.

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