}Expand description
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)
Sourcefn exotic_fact(
&self,
shape: &[usize],
) -> Result<Option<Box<dyn ExoticFact>>, Error>
fn exotic_fact( &self, shape: &[usize], ) -> Result<Option<Box<dyn ExoticFact>>, Error>
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§
Source§impl dyn TensorStorage
impl dyn TensorStorage
Sourcepub fn is<__T>(&self) -> boolwhere
__T: TensorStorage,
pub fn is<__T>(&self) -> boolwhere
__T: TensorStorage,
Returns true if the trait object wraps an object of type __T.
Sourcepub fn downcast<__T>(
self: Box<dyn TensorStorage>,
) -> Result<Box<__T>, Box<dyn TensorStorage>>where
__T: TensorStorage,
pub fn downcast<__T>(
self: Box<dyn TensorStorage>,
) -> Result<Box<__T>, Box<dyn TensorStorage>>where
__T: TensorStorage,
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.
Sourcepub fn downcast_rc<__T>(
self: Rc<dyn TensorStorage>,
) -> Result<Rc<__T>, Rc<dyn TensorStorage>>where
__T: TensorStorage,
pub fn downcast_rc<__T>(
self: Rc<dyn TensorStorage>,
) -> Result<Rc<__T>, Rc<dyn TensorStorage>>where
__T: TensorStorage,
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.
Sourcepub fn downcast_ref<__T>(&self) -> Option<&__T>where
__T: TensorStorage,
pub fn downcast_ref<__T>(&self) -> Option<&__T>where
__T: TensorStorage,
Returns a reference to the object within the trait object if it is of type __T, or
None if it isn’t.
Sourcepub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>where
__T: TensorStorage,
pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T>where
__T: TensorStorage,
Returns a mutable reference to the object within the trait object if it is of type
__T, or None if it isn’t.
