Trait implemented by matrix data storage that can provide a mutable access to its elements.

Note that a mutable access does not mean that the matrix owns its data. For example, a mutable matrix slice can provide mutable access to its elements even if it does not own its data (it contains only an internal reference to them).

Required Methods

fn ptr_mut(&mut self) -> *mut N

The matrix mutable data pointer.

impl<'a> Write for &'a mut [u8]impl<'a> Read for &'a [u8]

fn as_mut_slice(&mut self) -> &mut [N]

Retrieves the mutable data buffer as a contiguous slice.

Matrix components may not be contiguous, depending on its strides.

Provided Methods

unsafe fn get_address_unchecked_linear_mut(&mut self, i: usize) -> *mut N

Gets the mutable address of the i-th matrix component without performing bound-checking.

unsafe fn get_address_unchecked_mut(
    &mut self,
    irow: usize,
    icol: usize
) -> *mut N

Gets the mutable address of the i-th matrix component without performing bound-checking.

    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

unsafe fn get_unchecked_linear_mut(&mut self, i: usize) -> &mut N

Retrieves a mutable reference to the i-th element without bound-checking.

unsafe fn get_unchecked_mut(&mut self, irow: usize, icol: usize) -> &mut N

Retrieves a mutable reference to the element at (irow, icol) without bound-checking.

unsafe fn swap_unchecked_linear(&mut self, i1: usize, i2: usize)

Swaps two elements using their linear index without bound-checking.

unsafe fn swap_unchecked(
    &mut self,
    row_col1: (usize, usize),
    row_col2: (usize, usize)
)

Swaps two elements without bound-checking.
