Help migrating from 0.1.14 to 0.2.1

I'm working on updating from 0.1.14 to 0.2.1 and I'm wondering how to replace Interface::interrupt_in and it's use of RequestBuffer

This my existing code:

        let buf = RequestBuffer::new(1024);
        let bytes = porky.interface.interrupt_in(0x81, buf).await;
        if bytes.status.is_ok() {
            let msg = postcard::from_bytes(&bytes.data)?;
            return Ok(msg);
        }

Something like this:

// Ideally create this once on initialization, so maybe lift it out of a loop,
// or keep it in a field of `porky`. It's not too expensive to create every time if
// necessary, but only one instance can exist at a time for a given endpoint address.
let mut endpoint = interface.endpoint::<Interrupt, In>(0x81)?;

endpoint.submit(Buffer::new(1024));
let completion = endpoint.next_complete().await;
if completion.status.is_ok() {
    let msg = postcard::from_bytes(&completion.buffer)?;
    return Ok(msg);
}

Thanks! That compiles for sure. I'll test it this weekend and close the issue if all works.
Thanks again

thanks for that, will try as soon as I can. Buffer comes from transfer::in?
