I'd like to connect Controller to something which implements Read and Write. The tedious part of this is Controller::peek(usize), because you need to implement a small "peekable" buffer which applies to read_into as well.
peek feels like an implementation detail which bluetooth-hci could handle itself, so then you only would need to implement read_into. It also means bluetooth-hci can make this buffer as large or as small as needed.
BlueNRG has a buffer implementation which doesn't appear specific to this device:
