Function hurray_tensor_destroy 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn hurray_tensor_destroy(
    handle: *mut *mut HurrayTensor,
) -> HurrayStatus

Destroys a tensor handle — its descriptor, every buffer it owns, and its owner reference — then writes null through handle.

One call rather than two, so the teardown order is not the caller’s problem. A non-null owner_release is invoked exactly once, with the owner pointer given at construction.

Safety

• handle MUST be a valid, non-null pointer to a *mut HurrayTensor produced by hurray_tensor_new, by hurray_reader_next_tensor, by hurray_file_reader_read_tensor, or taken out of a native-protocol capsule.
• That tensor MUST NOT have been destroyed already.

Examples

use hurray_ffi::tensor::{hurray_tensor_destroy, hurray_tensor_new};
use hurray_ffi::{
    hurray_buffer_list_new, HurrayBufferList, HurrayTensor, HURRAY_C_ABI_VERSION,
    HURRAY_ERR_INTERNAL, HURRAY_OK,
};
assert_eq!(unsafe { hurray_tensor_destroy(&mut tensor) }, HURRAY_OK);
assert!(tensor.is_null());

// A second destroy finds the caller's variable dead and says so, rather than
// freeing anything twice.
assert_eq!(
    unsafe { hurray_tensor_destroy(&mut tensor) },
    HURRAY_ERR_INTERNAL,
);
