Method new_async

crates/cust/src/memory/device/device_box.rs:86–90

Allocates device memory asynchronously and asynchronously copies `val` into it. This doesn't actually allocate if `T` is zero-sized. If the memory behind `val` is not page-locked (pinned), a staging buffer will be allocated using a worker thread. If you are going to be making many asynchronous copies, it is generally a good idea to keep the data as a [`crate::memory::LockedBuffer`] or [`crate::m

(val: &T, stream: &Stream)

    /// # Ok(())

    pub unsafe fn new_async(val: &T, stream: &Stream) -> CudaResult<Self> {
        let mut dev_box = DeviceBox::uninitialized_async(stream)?;
        dev_box.async_copy_from(val, stream)?;
        Ok(dev_box)
    }

    /// particular stream. The stream will free the allocation as soon as it reaches
