👋 I'm new to rust and struggling with lifetime woes for embedded dev. I have a
triple-buffered frame buffer and trying to DMA the contents of one of the
buffers to the display. I think I have everything else working for the writing
of the buffers, but doing the DMA transfer is an async operation and the view
callback I wrote doesn't play nicely with the static Hub75 display driver.

More details in the thread.
