Defines operations common to both TooDee and TooDeeViewMut. Default implementations are provided where possible/practical.

Required methods

fn view_mut(&mut self, start: Coordinate, end: Coordinate) -> TooDeeViewMut<T>

Returns a mutable view (or subset) of the current area based on the coordinates provided.

fn rows_mut(&mut self) -> RowsMut<T>

Returns a mutable iterator of slices, where each slice represents the entire row of the object's area.

fn col_mut(&mut self, col: usize) -> ColMut<T>

Returns a mutable iterator over a single column

Provided methods

fn cells_mut(&mut self) -> CellsMut<T>

Returns an iterator that traverses all cells within the area.

fn fill<V>(&mut self, fill: V) where
    V: Borrow<T>,
    T: Clone, 

Fills the entire area with the specified value.

fn swap_cols(&mut self, c1: usize, c2: usize)

Swap/exchange the data between two columns.

fn swap_rows(&mut self, r1: usize, r2: usize)

Swap/exchange the data between two rows.

Panics

Panics if either row index is out of bounds.

fn row_pair_mut(&mut self, r1: usize, r2: usize) -> (&mut [T], &mut [T])

Return the specified rows as mutable slices.

Panics

Will panic if r1 and r2 are equal, or if either row index is out of bounds.
