Struct DLPackTensor 

pub struct DLPackTensor { /* private fields */ }

Opaque handle to a DLPack DLManagedTensor.

This is a GPU tensor representation used for zero-copy exchange with frameworks like PyTorch and CuPy.

Requirements

• All columns must have the same numeric data type.
• Null count must be zero for all columns.

Implementations

impl DLPackTensor

pub fn from_table(table: &Table) -> Result<Self>

Convert a table to a DLPack tensor.

Errors

Returns an error if columns have different types, non-numeric types, or non-zero null counts.

pub fn to_table(self) -> Result<Table>

Import a table from this DLPack tensor, consuming the tensor.

pub fn as_raw_ptr(&self) -> usize

Get the raw DLManagedTensor* pointer as usize.

This is useful for passing to Python / C frameworks. The caller must NOT free the tensor; it is still owned by this handle.

pub unsafe fn from_raw_ptr(ptr: usize) -> Self

Create from a raw DLManagedTensor* pointer.

Safety

The pointer must be a valid DLManagedTensor* with a working deleter.

Trait Implementations

impl Drop for DLPackTensor

fn drop(&mut self)

Executes the destructor for this type.
