Performs the + operation.

impl<'a, 'b, T> Index<&'b [usize]> for NDSlice<'a, T>

type Output = T

The returned type after indexing.

fn index<'c>(&'c self, idx: &'b [usize]) -> &'c T

Performs the indexing (container[index]) operation.

impl<'a, 'b, T> Index<&'b [usize; 1]> for NDSlice<'a, T>

type Output = T

The returned type after indexing.

fn index<'c>(&'c self, idx: &'b [usize; 1]) -> &'c T

Performs the indexing (container[index]) operation.

impl<'a, 'b, T> Index<&'b [usize; 2]> for NDSlice<'a, T>

type Output = T

The returned type after indexing.

fn index<'c>(&'c self, idx: &'b [usize; 2]) -> &'c T

Performs the indexing (container[index]) operation.

impl<'a, 'b, T> Index<&'b [usize; 3]> for NDSlice<'a, T>

type Output = T

The returned type after indexing.

fn index<'c>(&'c self, idx: &'b [usize; 3]) -> &'c T

Performs the indexing (container[index]) operation.

impl<'a, 'b, 'c, T: Clone + Display + From<f32>, R: NDData<T> + Sized> Mul<&'a R> for &'b NDSlice<'c, T>

where NDArray<T>: Blas<T>,

type Output = NDArray<T>

The resulting type after applying the * operator.

fn mul(self, rhs: &'a R) -> NDArray<T>

Performs the * operation.

impl<'a, T> NDData<T> for NDSlice<'a, T>

fn shape(&self) -> &[usize]

Return a slice of length N where each element is the length of the dimension. For a 2 dimensional matrix, the first dimension is the number of rows and the second dimension is the number of columns.

fn strides(&self) -> &[usize]

Return a slice of length N where each element is the stride of the dimension.

fn get_data(&self) -> &[T]

Return the underlying storage array as a slice.

fn dim(&self) -> usize

Return N, the number of dimensions.

fn size(&self) -> usize

Return the total number of element of the N-dimensional array.

fn idx<'a>(&'a self, idx: &[usize]) -> &'a T

Take a slice of length N representing an N-dimensional index in the array and return a reference to the element at this position.

impl<'a, T: 'a> NDSliceable<'a, T> for NDSlice<'a, T>

fn slice(&'a self, idx: &[usize]) -> NDSlice<'a, T>

Take a slice of length < N representing the sub slice index and return immutable borrow of the sub slice as an NDSlice. Because the storage is in row-major order and the slice need to be contiguous in the underlying storage array it means, for example, only the rows of a matrix can be borrowed.

impl<'a, T: PartialEq, O: NDData<T> + Sized> PartialEq<O> for NDSlice<'a, T>

fn eq(&self, other: &O) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, T> SizedBuffer for NDSlice<'a, T>

unsafe fn get_raw_ptr(&self) -> *const c_void

fn get_raw_size(&self) -> usize

impl<'a, 'b, 'c, T: Clone + Display + From<f32>, R: NDData<T> + Sized> Sub<&'a R> for &'b NDSlice<'c, T>

where NDArray<T>: Blas<T>,

type Output = NDArray<T>

The resulting type after applying the - operator.

fn sub(self, rhs: &'a R) -> NDArray<T>

Performs the - operation.
