Struct TensorOwnedView 

pub struct TensorOwnedView { /* private fields */ }

Owned lazy tensor view over a shared base tensor.

This stores only ownership of the base allocation plus logical layout metadata. Borrow it as TensorRead and materialize it through an active backend session when compact storage is required.

Implementations

impl TensorOwnedView

pub fn from_tensor(base: Arc<Tensor>) -> Self

Create an owned view preserving the base tensor’s current layout.

pub fn from_parts( base: Arc<Tensor>, shape: Vec<usize>, strides: Vec<isize>, offset: isize, ) -> Result<Self>

Create an owned view with explicit layout metadata.

Errors

Returns crate::Error::Validation with tenferro_tensor_core::ValidationError::RankMismatch when shape and strides have different ranks, tenferro_tensor_core::ValidationError::ViewOutOfBounds when the layout exceeds the base tensor buffer, or tenferro_tensor_core::ValidationError::IntegerOverflow for layout arithmetic overflow.

pub fn dtype(&self) -> DType

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

pub fn strides(&self) -> &[isize]

pub fn offset(&self) -> isize

pub fn tensor_view(&self) -> TensorView<'_>

pub fn tensor_read(&self) -> TensorRead<'_>

pub fn transpose_view(&self, axes: impl AsRef<[usize]>) -> Result<Self>

Errors

Returns crate::Error::Validation with tenferro_tensor_core::ValidationError::InvalidPermutationLength, tenferro_tensor_core::ValidationError::AxisOutOfBounds, or tenferro_tensor_core::ValidationError::DuplicateAxis when axes is not a valid permutation of the view rank.

pub fn reshape_view(&self, shape: impl IntoShapeVec) -> Result<Self>

Errors

Returns crate::Error::Validation with tenferro_tensor_core::ValidationError::NonContiguousViewAsSlice when the source is not compact column-major, tenferro_tensor_core::ValidationError::ShapeMismatch (whose tenferro_tensor_core::ShapeMismatch::ReshapeElementCount source records the counts) when element counts differ, tenferro_tensor_core::ValidationError::IntegerOverflow for shape arithmetic overflow, or tenferro_tensor_core::ValidationError::ViewOutOfBounds when the reshaped view exceeds the base buffer.

pub fn slice_view(&self, config: &SliceConfig) -> Result<Self>

Errors

Returns crate::Error::Validation with tenferro_tensor_core::ValidationError::RankMismatch when a slice vector does not match the view rank, tenferro_tensor_core::ValidationError::InvalidArgument when a bound or stride cannot be represented or is invalid, tenferro_tensor_core::ValidationError::InvalidSliceStep or tenferro_tensor_core::ValidationError::InvalidSliceBounds for slice parameters, tenferro_tensor_core::ValidationError::IntegerOverflow for slice arithmetic overflow, or tenferro_tensor_core::ValidationError::ViewOutOfBounds when the result exceeds the base buffer.

pub fn broadcast_in_dim_view( &self, shape: impl IntoShapeVec, dims: impl AsRef<[usize]>, ) -> Result<Self>

Errors

Returns crate::Error::Validation with tenferro_tensor_core::ValidationError::RankMismatch, tenferro_tensor_core::ValidationError::AxisOutOfBounds, or tenferro_tensor_core::ValidationError::DuplicateAxis for invalid dimension mappings, tenferro_tensor_core::ValidationError::ShapeDataLengthMismatch for incompatible extents, tenferro_tensor_core::ValidationError::ViewOutOfBounds when the result exceeds the base buffer, or tenferro_tensor_core::ValidationError::IntegerOverflow for layout arithmetic overflow.
