pub fn decode_setpoint_reference(
data: &[u8],
) -> Result<Option<BACnetObjectPropertyReference>, Error>Expand description
Decode a whole property-value payload as the BACnetSetpointReference
form, the frame read by decode_setpoint_reference_at, which must use
all of data.
The production’s one member is optional, and an absent member has no
encoding (Clause 20.2.16), so an empty payload is the value without a
reference and yields None: Clause 12.17.16 then takes the setpoint from
the Loop’s Setpoint property.
