    N: Scalar,
    Alloc: Allocator<N, R, C>, 

type RStride = RStride

The static stride of this storage's rows.

type CStride = CStride

The static stride of this storage's columns.

type Alloc = Alloc

The allocator for this family of storage.

fn into_owned(self) -> Owned<N, R, C, Self::Alloc>

Builds a matrix data storage that does not contain any reference.

fn clone_owned(&self) -> Owned<N, R, C, Self::Alloc>

Clones this data storage into one that does not contain any reference.

fn ptr(&self) -> *const N

The matrix data pointer.

fn shape(&self) -> (R, C)

The dimension of the matrix at run-time. Arr length of zero indicates the additive identity element of any dimension. Must be equal to Self::dimension() if it is not None.

fn strides(&self) -> (Self::RStride, Self::CStride)

The spacing between concecutive row elements and consecutive column elements.

fn linear_index(&self, irow: usize, icol: usize) -> usize

Compute the index corresponding to the irow-th row and icol-th column of this matrix. The index must be such that the following holds:

unsafe fn get_address_unchecked_linear(&self, i: usize) -> *const N

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

unsafe fn get_address_unchecked(&self, irow: usize, icol: usize) -> *const N

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

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

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

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

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

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.

    &mut self,
    row_col1: (usize, usize),
    row_col2: (usize, usize)
)
