Crate dlpark 

Safe ownership and interoperability helpers for DLPack.

Producers convert into a Builder, which keeps the producer alive until it builds a ManagedBox. ManagedBox calls the DLPack deleter on drop.

use dlpark::{Builder, DlpackFlags, versioned};
use ndarray::arr1;

let array = Box::new(arr1(&[1_i32, 2, 3]));
let tensor: versioned::Dlpack = Builder::from(array)
    .insert_flags(DlpackFlags::READ_ONLY)
    .unwrap()
    .try_build()
    .unwrap();
assert_eq!(tensor.shape().unwrap(), &[3]);

legacy::Dlpack uses DLManagedTensor; versioned::Dlpack uses DLManagedTensorVersioned and exposes version and flags.
