This is a small nit...
It would be nice to zero out the
MQTTProperty
union/value before reading fields into it. That would leave any unused space predictably set to zero.On advantage is that if you accidentally read an 8 or 16-bit value out using a larger field size (i.e. read as a u32) you still get the correct numeric value.
(Wonder what made me think to do this).
