Struct Grid

pub struct Grid<T> {
    pub cells: Vec<Option<T>>,
    pub rows: Vec<NotNan<fsize>>,
    pub cols: Vec<NotNan<fsize>>,
    pub n_rows: usize,
    pub n_cols: usize,
    pub n_elements: usize,
}

Representation of a grid of optional elements of type T Divided into rows and columns, where each row and column has a unique coordinate

Fields

cells: Vec<Option<T>>

rows: Vec<NotNan<fsize>>

cols: Vec<NotNan<fsize>>

n_rows: usize

n_cols: usize

n_elements: usize

Implementations

impl<T> Grid<T>

pub fn new(elements: Vec<(T, Point)>) -> Self

Creates a new grid from a vector of values of type T and their coordinates

pub fn rows_in_range( &self, y_range: RangeInclusive<fsize>, ) -> RangeInclusive<usize>

pub fn cols_in_range( &self, x_range: RangeInclusive<fsize>, ) -> RangeInclusive<usize>

pub fn get_neighbors(&self, idx: usize) -> [usize; 8]

Returns the indices of the 8 directly neighboring cells. If the cell is on the edge, the index of the cell itself is returned instead for neighbors out of bounds

pub fn to_index(&self, row: usize, col: usize) -> Result<usize, OutOfBounds>

pub fn to_row_col(&self, index: usize) -> Option<(usize, usize)>

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)

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.
