Struct TypedTensor 

pub struct TypedTensor<T, R: TensorRank = DynRank> { /* private fields */ }

Runtime typed tensor storage with compile-time scalar type and rank metadata.

Owned tensors are compact column-major. Arbitrary strides and metadata-only layout changes are represented by TypedTensorView and TypedTensorViewMut. The buffer may be host-backed or backend-backed; host-inspection methods do not download backend buffers implicitly.

Examples

use tenferro_tensor::{Rank, Tensor, TypedTensor};

let t = TypedTensor::<f64>::from_vec_col_major(vec![2, 2], vec![1.0, 2.0, 3.0, 4.0]).unwrap();
assert_eq!(t.shape(), &[2, 2]);

let static_rank = TypedTensor::<f64, Rank<2>>::from_vec_col_major([2, 2], vec![1.0; 4]).unwrap();
assert_eq!(static_rank.rank(), 2);

let dynamic = Tensor::from_vec_col_major(vec![2, 2], vec![1.0_f64; 4]).unwrap();
assert_eq!(dynamic.shape(), &[2, 2]);

The R parameter stores rank metadata. It defaults to dynamic rank (DynRank); use Rank<N> for compile-time rank validation. The dtype-erased Tensor enum remains dynamic-rank.

assert_eq!(unsafe { *t.get_unchecked(&[1])? }, 2.0);

impl<T, R: TensorRank> TypedTensor<T, R>

pub fn from_buffer_col_major( shape: impl Into<R::Shape>, buffer: Buffer<T>, placement: Placement, ) -> Result<Self>

where T: 'static,

Create a tensor from an existing buffer and compact column-major layout.

This preserves the owned tensor invariant that layout metadata is compact column-major, including for backend-owned buffers.

Examples

use tenferro_tensor::{Buffer, Placement, TypedTensor};

let tensor = TypedTensor::<f64>::from_buffer_col_major(
    vec![2],
    Buffer::Host(vec![1.0, 2.0]),

        memory_kind: tenferro_tensor::MemoryKind::UnpinnedHost,
        device: None,
        cpu_affinity: None,
    },
)
.unwrap();
assert_eq!(tensor.shape(), &[2]);

Errors

Returns crate::Error::Validation with tenferro_tensor_core::ValidationError::ShapeDataLengthMismatch when the shape product differs from the buffer length, tenferro_tensor_core::ValidationError::IntegerOverflow when shape or stride arithmetic overflows, or tenferro_tensor_core::ValidationError::RankMismatch when a supplied rank-specific shape cannot be represented.

pub fn try_into_rank<const N: usize>(self) -> Result<TypedTensor<T, Rank<N>>>

Convert this tensor into static rank metadata after validating its rank.

The buffer and placement are preserved. This method changes only the compile-time rank marker on the owned compact column-major tensor.

Examples

use tenferro_tensor::{Rank, TypedTensor};

let tensor = TypedTensor::<f64>::from_vec_col_major(vec![2, 3], vec![1.0; 6]).unwrap();
let ranked: TypedTensor<f64, Rank<2>> = tensor.try_into_rank::<2>()?;

Errors

Returns crate::Error::Validation with tenferro_tensor_core::ValidationError::RankMismatch when the typed rank does not match the existing shape, tenferro_tensor_core::ValidationError::IntegerOverflow when compact strides cannot be computed, or tenferro_tensor_core::ValidationError::ViewOutOfBounds when the preserved buffer cannot hold the rank-converted layout.

pub fn n_elements(&self) -> usize

Number of elements in the tensor.

Examples

use tenferro_tensor::TypedTensor;

assert_eq!(t.layout().strides(), &[1, 2]);

pub fn buffer(&self) -> &Buffer<T>

Return the storage backing this tensor.

This is an explicit storage-inspection API for backend glue and tests. Host value inspection should prefer TypedTensor::host_data when the caller requires host storage.

Examples

let t = TypedTensor::<f64>::from_vec_col_major(vec![2], vec![1.0, 2.0]).unwrap();
assert!(matches!(t.buffer(), Buffer::Host(_)));

where T: 'static,

Return the stable physical backend allocation identity.

Examples

use tenferro_tensor::{MemoryKind, TypedTensor};

let t = TypedTensor::<f64>::from_vec_col_major(vec![1], vec![1.0]).unwrap();
assert_eq!(t.placement().memory_kind, MemoryKind::UnpinnedHost);

pub fn set_placement(&mut self, placement: Placement)

Replace placement metadata without changing the storage buffer.

Examples

use tenferro_tensor::{MemoryKind, Placement, TypedTensor};

let mut t = TypedTensor::<f64>::from_vec_col_major(vec![1], vec![1.0]).unwrap();
t.set_placement(Placement {
    memory_kind: MemoryKind::PinnedHost,
    device: None,
    cpu_affinity: None,
});
assert_eq!(t.placement().memory_kind, MemoryKind::PinnedHost);

pub fn set_cpu_affinity(&mut self, cpu_affinity: Option<CpuDomainId>)

Replace only CPU routing/locality metadata without changing storage.

Device, memory kind, backend allocation domain, and allocation identity remain unchanged.

Examples

use tenferro_tensor::{CpuDomainId, TypedTensor};

let mut tensor = TypedTensor::<f64>::from_vec_col_major(vec![1], vec![1.0])?;
tensor.set_cpu_affinity(Some(CpuDomainId::new(4)));
assert_eq!(tensor.placement().cpu_affinity, Some(CpuDomainId::new(4)));

pub fn as_view(&self) -> TypedTensorView<'_, T, R>

where T: 'static,

Borrow this tensor as a typed view preserving rank and layout metadata.

use tenferro_tensor::{Rank, TypedTensor};

let tensor = TypedTensor::<f64, Rank<2>>::from_vec_col_major([2, 2], vec![1.0; 4]).unwrap();
let view = tensor.as_view();
assert_eq!(view.strides(), &[1, 2]);

pub fn as_view_mut(&mut self) -> TypedTensorViewMut<'_, T, R>

where T: 'static,

Mutably borrow this tensor as a typed view preserving rank and layout metadata.

Examples

use tenferro_tensor::TypedTensor;

let mut tensor = TypedTensor::<i32>::from_vec_col_major(vec![1], vec![1]).unwrap();
*tensor.as_view_mut().get_mut(&[0]).unwrap() = 2;
assert_eq!(tensor.as_slice().unwrap(), &[2]);

pub fn backend_region_view( &self, shape: Vec<usize>, strides: Vec<isize>, offset: isize, ) -> Result<TypedTensorView<'_, T, DynRank>>

where T: 'static,

Borrow a read-only strided region view over this tensor’s backend (device) buffer from explicit layout metadata.

This is a metadata-only view: no data is copied or transferred. The layout’s reachable element span is validated against the backend buffer’s physical length. Host-backed tensors are rejected with an explicit backend error; host regions are expressed with TypedTensorView::from_slice over host storage instead.

Examples

use tenferro_tensor::TypedTensor;

// Host tensors are rejected: this constructor is for backend buffers.
let host = TypedTensor::<f64>::from_vec_col_major(vec![4], vec![0.0; 4]).unwrap();
let err = host.backend_region_view(vec![2, 2], vec![1, 2], 0).unwrap_err();
assert!(err.to_string().contains("backend"));

Errors

Returns crate::Error::RuntimeState when this tensor is host-backed; backend region views require a backend buffer. It returns crate::Error::Validation with tenferro_tensor_core::ValidationError::RankMismatch for incompatible shape/stride ranks, tenferro_tensor_core::ValidationError::ViewOutOfBounds when the region exceeds the backend buffer, or tenferro_tensor_core::ValidationError::IntegerOverflow for layout arithmetic overflow.

pub fn backend_region_view_mut( &mut self, shape: Vec<usize>, strides: Vec<isize>, offset: isize, ) -> Result<TypedTensorViewMut<'_, T, DynRank>>

where T: 'static,

Borrow a mutable strided region view over this tensor’s backend (device) buffer from explicit layout metadata.

This is the mutable counterpart of TypedTensor::backend_region_view. The layout’s reachable element span is validated against the backend buffer’s physical length, and layouts whose logical elements alias the same physical element are rejected. Host-backed tensors are rejected with an explicit backend error; mutable host regions must go through TypedTensorViewMut::try_multi_slice_mut or host constructors.

Backend buffers are shared handles, so distinct region views over one buffer can coexist; disjointness between regions used concurrently by backend operations is the caller’s contract (as with BLAS-style in-place update APIs).

Examples

use tenferro_tensor::TypedTensor;

// Host tensors are rejected: this constructor is for backend buffers.
let mut host = TypedTensor::<f64>::from_vec_col_major(vec![4], vec![0.0; 4]).unwrap();
let err = host.backend_region_view_mut(vec![2, 2], vec![1, 2], 0).unwrap_err();
assert!(err.to_string().contains("backend"));

Errors

Returns crate::Error::RuntimeState when this tensor is host-backed; mutable backend region views require a backend buffer. It returns crate::Error::Validation with tenferro_tensor_core::ValidationError::RankMismatch for incompatible shape/stride ranks, tenferro_tensor_core::ValidationError::ViewOutOfBounds when the region exceeds the backend buffer, tenferro_tensor_core::ValidationError::OverlappingMutableLayout when logical elements alias, or tenferro_tensor_core::ValidationError::IntegerOverflow for layout arithmetic overflow.

pub fn into_layout(self) -> TensorLayout<R>

Consume this tensor and return its layout metadata.

Examples

use tenferro_tensor::TypedTensor;

let t = TypedTensor::<f64>::from_vec_col_major(vec![2], vec![1.0, 2.0]).unwrap();

let (buffer, layout, placement) = t.into_parts();
assert!(matches!(buffer, Buffer::Host(_)));
assert_eq!(layout.shape(), &[2]);
assert!(placement.device.is_none());

pub fn as_slice(&self) -> Result<&[T]>

let typed = TypedTensor::from_vec_col_major(vec![2], vec![1.0_f32, 2.0]).unwrap();
let tensor: Tensor = typed.into();
assert_eq!(tensor.shape(), &[2]);

fn from(t: TypedTensor<f32>) -> Self

Converts to this type from the input type.

impl From<TypedTensor<f64>> for Tensor

Wrap an f64 TypedTensor into the corresponding Tensor variant.

Examples

use tenferro_tensor::{Tensor, TypedTensor};

let typed = TypedTensor::from_vec_col_major(vec![2], vec![1.0_f64, 2.0]).unwrap();
let tensor: Tensor = typed.into();
assert_eq!(tensor.shape(), &[2]);

fn from(t: TypedTensor<f64>) -> Self
