Trait StorageMut

Trait for backing storage used by mutable tensors and views.

This extends Storage with methods to get mutable pointers and references to elements in the storage.

Safety

The as_mut_ptr method has the same safety requirements as Storage::as_ptr. The result of as_mut_ptr must also be equal to as_ptr.

Required Methods

fn as_mut_ptr(&mut self) -> *mut Self::Elem

Return a mutable pointer to the first element in storage.

Provided Methods

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

Mutable version of Storage::get.

Safety

This has the same safety requirements as get.

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

Mutable version of Storage::get_unchecked.

Safety

This has the same requirement as get_mut plus the caller must ensure that offset < self.len().

fn slice_mut(&mut self, range: Range<usize>) -> ViewMutData<'_, Self::Elem>

Return a slice of this storage.

fn view_mut(&mut self) -> ViewMutData<'_, Self::Elem>

Return a mutable view of this storage.

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

Return the stored elements as a mutable slice.

Safety

The caller must ensure that the storage is contiguous (ie. no unused elements) and that there are no other references to any elements in the storage.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
