Crate spatialrust_tensor 

Small, runtime-independent tensor descriptors and CPU storage views.

Shape, element strides, byte offset, device, and ownership are explicit. This crate never uploads, downloads, or otherwise migrates storage. DLPack FFI and image bridges are additive features built on this data model.

Structs

DataType

Scalar category, bit width, and vector lane count.

Device

Device category and backend-local ordinal.

DlpackExport

Owner for a versioned DLPack managed tensor exported without copying CPU data.

DlpackImport

Validated owner of a DLPack producer’s managed tensor.

DlpackLegacyExport

Owner for a legacy DLPack managed tensor exported without copying CPU data.

TensorBuffer

Owned host allocation paired with a validated tensor descriptor.

TensorDescriptor

Shape, element strides, type, offset, and device for one tensor.

TensorView

Lifetime-bound, zero-copy view of host-accessible tensor storage.

Enums

DataTypeCode

DLPack-compatible scalar category without depending on a runtime header.

DeviceKind

Device category represented independently of any execution backend.

DlpackError

Errors raised while validating a DLPack managed tensor.

Ownership

Whether a tensor object owns or borrows its backing allocation.

SpatialTensorBridgeError

Errors raised while exposing a point-cloud column as a generic tensor.

TensorError

Tensor construction and layout errors.

Constants

DLPACK_MAJOR

DLPack ABI major version supported by this boundary.

DLPACK_MINOR

Baseline DLPack minor version emitted by this boundary.

Traits

HostTensorStorage

Runtime-owned, host-accessible storage retained without a runtime dependency.

TensorElement

A native-endian scalar that has a stable tensor dtype and no invalid bit patterns.

Functions

interleaved_image_view

Borrows a packed interleaved image as a zero-copy [height, width, channels] tensor.

pack_interleaved_image

Explicitly packs a possibly strided interleaved image view into an owned HWC tensor.

pack_planar_image

Explicitly packs a possibly strided planar image view into an owned CHW tensor.

planar_image_view

Borrows a packed planar image as a zero-copy [channels, height, width] tensor.

release_dlpack_legacy_raw^⚠

Calls the producer deleter for a legacy raw pointer.

release_dlpack_raw^⚠

Calls the producer deleter for a raw pointer previously returned by DlpackExport::into_raw.

spatial_f32_field_view

Borrows one f32 point field as a zero-copy [point_count] CPU tensor.
