Struct block_grid::BlockMut[−][src]

pub struct BlockMut<'a, T, B: BlockDim> { /* fields omitted */ }

A mutable view of a 2D block contiguous in memory.

Can be obtained via BlockIterMut, which is created by calling BlockGrid::block_iter_mut.

Implementations

impl<'a, T, B: BlockDim> BlockMut<'a, T, B>[src]

pub fn coords(&self) -> Coords[src]

Returns the coordinates of the entire block.

Block coordinates mean that the (i, j) refers to the i-th row of blocks and the j-th block in that row. If you need the coordinates of the first (top-left) element, use starts_at instead.

pub fn starts_at(&self) -> Coords[src]

Returns of the coordinates of the first (top-left) element in the block.

pub fn contains(&self, (row, col): Coords) -> bool[src]

Returns true if the given coordinates are valid.

pub fn get(&self, coords: Coords) -> Option<&T>[src]

Returns a reference to the element at the given coordinates, or None if they are out-of-bounds.

pub fn get_mut(&mut self, coords: Coords) -> Option<&mut T>[src]

Returns a mutable reference to the element at the given coordinates, or None if they are out-of-bounds.

pub unsafe fn get_unchecked(&self, coords: Coords) -> &T[src]

Returns a reference to the element at the given coordinates, without bounds checking.

Safety

Calling this method with out-of-bounds coordinates is undefined-behaviour.

pub unsafe fn get_unchecked_mut(&mut self, coords: Coords) -> &mut T[src]

Returns a mutable reference to the element at the given coordinates, without bounds checking.

Safety

Calling this method with out-of-bounds coordinates is undefined-behaviour.

pub fn raw(&self) -> &[T][src]

Returns all elements in block as a slice in memory order.

pub fn raw_mut(&mut self) -> &mut [T][src]

Returns all elements in block as a mutable slice in memory order.
