Enum EventTransition 

pub enum EventTransition {
    ToOffnormal,
    ToFault,
    ToNormal,
}

Event transition category per ASHRAE 135-2020 Clause 13.2.5.

Variants

ToOffnormal

Transition to an off-normal state (OFFNORMAL, HIGH_LIMIT, LOW_LIMIT, etc.).

ToFault

Transition to FAULT.

ToNormal

Transition to NORMAL.

Implementations

impl EventTransition

pub fn for_target_state(state: EventState) -> Self

Classify a destination event state under ASHRAE 135-2020 Clause 13.2.

NORMAL and FAULT are the only states outside the offnormal category, as also specified by Clause 13.2.2.1.2. Therefore the residual case is deliberately TO_OFFNORMAL, not TO_FAULT.

pub fn bit_mask(self) -> EventTransitionBits

This transition’s flag in a BACnetEventTransitionBits value, such as Event_Enable, Acked_Transitions, Ack_Required or a BACnetDestination’s transitions.

pub fn index(self) -> usize

Positional index into the NotificationClass PRIORITY array, ordered [TO_OFFNORMAL, TO_FAULT, TO_NORMAL]. ACK_REQUIRED is a bit string: test it with EventTransition::bit_mask.
