}

Trait abstracting over tensor storage backends.

PlainStorage is the primary implementation backed by a contiguous Blob. Non-plain backends are held behind StorageKind::Exotic(Box<dyn TensorStorage>).

Required Methods

fn byte_len(&self) -> usize

fn is_empty(&self) -> bool

fn deep_clone(&self) -> Box<dyn TensorStorage>

fn as_plain(&self) -> Option<&PlainStorage>

fn as_plain_mut(&mut self) -> Option<&mut PlainStorage>

fn into_plain(self: Box<Self>) -> Option<PlainStorage>

fn dyn_hash(&self, state: &mut dyn Hasher)

fn exotic_fact( &self, shape: &[usize], ) -> TractResult<Option<Box<dyn ExoticFact>>>

Build the ExoticFact that describes this storage for use in TypedFact.

Plain storage returns None. Exotic storages should return the appropriate fact so that From<Arc<Tensor>> for TypedFact preserves exotic-ness.

Implementations

impl dyn TensorStorage

pub fn is<__T: TensorStorage>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T: TensorStorage>( self: Box<Self>, ) -> Result<Box<__T>, Box<Self>>

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T: TensorStorage>( self: Rc<Self>, ) -> Result<Rc<__T>, Rc<Self>>

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T: TensorStorage>(&self) -> Option<&__T>

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T: TensorStorage>(&mut self) -> Option<&mut __T>

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.

Trait Implementations

impl<'eq> PartialEq<&Box<dyn TensorStorage + 'eq>> for Box<dyn TensorStorage + 'eq>

fn eq(&self, other: &&Self) -> 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.
