type RStride = RStride

The static stride of this storage's rows.

type CStride = CStride

The static stride of this storage's columns.

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
) -> (<SliceStorage<'a, N, R, C, RStride, CStride> as Storage<N, R, C>>::RStride, <SliceStorage<'a, N, R, C, RStride, CStride> as Storage<N, R, C>>::CStride)

The spacing between consecutive row elements and consecutive column elements.

fn is_contiguous(&self) -> bool

Indicates whether this data buffer stores its elements contiguously.

fn into_owned(self) -> <DefaultAllocator as Allocator<N, R, C>>::Buffer where
    DefaultAllocator: Allocator<N, R, C>, 

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

fn clone_owned(&self) -> <DefaultAllocator as Allocator<N, R, C>>::Buffer where
    DefaultAllocator: Allocator<N, R, C>, 

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