Trait Implementations

impl<'a, N: Scalar, R: Dim, C: Dim, RStride: Dim, CStride: Dim> Storage<N, R, C> for SliceStorageMut<'a, N, R, C, RStride, CStride>

type RStride = RStride

type CStride = CStride

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

fn strides(&self) -> (Self::RStride, Self::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) -> Owned<N, R, C> where
    DefaultAllocator: Allocator<N, R, C>, 

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

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

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

fn as_slice(&self) -> &[N]

Retrieves the data buffer as a contiguous slice.

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

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.

impl<'a, N: Scalar, R: Dim, C: Dim, RStride: Dim, CStride: Dim> StorageMut<N, R, C> for SliceStorageMut<'a, N, R, C, RStride, CStride>
