Enum CowData 

pub enum CowData<'a, T> {
    Owned(Vec<T>),
    Borrowed(ViewData<'a, T>),
}

Tensor storage which may be either owned or borrowed.

The name is taken from std::borrow::Cow in the standard library, which is conceptually similar.

Variants

Owned(Vec<T>)

A CowData that owns its data.

Borrowed(ViewData<'a, T>)

A CowData that borrows data.

Trait Implementations

impl<T> Storage for CowData<'_, T>

const MUTABLE: bool = false

True if this storage allows mutable access via StorageMut. This is used to determine if a layout can be safely used with a storage. Layouts where multiple indices map to the same offset must not be used with mutable storage.

type Elem = T

The element type.

fn len(&self) -> usize

Return the number of elements in the storage.

fn as_ptr(&self) -> *const T

Return a pointer to the first element in the storage.

fn is_empty(&self) -> bool

Return true if the storage contains no elements.

unsafe fn get(&self, offset: usize) -> Option<&Self::Elem>

Return the element at a given offset, or None if offset >= self.len().

unsafe fn get_unchecked(&self, offset: usize) -> &Self::Elem

Return a reference to the element at offset.

fn slice(&self, range: Range<usize>) -> ViewData<'_, Self::Elem>

Return a view of a sub-region of the storage.

fn view(&self) -> ViewData<'_, Self::Elem>

Return an immutable view of this storage.

unsafe fn as_slice(&self) -> &[Self::Elem]

Return the contents of the storage as a slice.
