Method process_ff_upload

src/uinput.rs:334–346

Processes the given [`UInputEvent`] if it is a force feedback upload event, in which case this function will start the force feedback upload and claim ownership over the [`UInputEvent`] and return a [`FFUploadEvent`] instead. The returned event allows the user to allocate and set the effect ID as well as access the effect data. # Panics This function will panic if `event.code()` is not `UI_FF_U
