Fields

device_type: i32

device_id: i32

array: *mut FFI_ArrowArray

schema: *mut FFI_ArrowSchema

release: Option<unsafe extern "C" fn(*mut ArrowDeviceArray)>

private_data: *mut c_void

Implementations

impl ArrowDeviceArray

pub unsafe fn new( device_type: i32, device_id: i32, array: *mut FFI_ArrowArray, schema: *mut FFI_ArrowSchema, ) -> ArrowDeviceArrayOwned

Adopt heap-owned Arrow FFI objects containing ready device allocations.

Safety

array and schema must each come from Box::into_raw, be uniquely transferred, and describe live producer-ready device memory. Their buffers and callbacks must support use and release from any host thread; further producer accesses must be coordinated with the recipient.
