Struct EventStateChange 

pub struct EventStateChange {
    pub from: EventState,
    pub to: EventState,
}

A detected change in event state.

Fields

from: EventState

The previous event state.

to: EventState

The new event state.

Implementations

impl EventStateChange

pub fn event_type(&self) -> EventType

Derive the BACnet EventType from the state transition.

If either the from or to state is HIGH_LIMIT or LOW_LIMIT, the event type is OUT_OF_RANGE. Otherwise it is CHANGE_OF_STATE.

pub fn transition(&self) -> EventTransition

Derive the event transition category from the state change.

Per Clause 13.2.5:

• to == NORMAL → ToNormal
• to == FAULT → ToFault
• Everything else (OFFNORMAL, HIGH_LIMIT, LOW_LIMIT) → ToOffnormal

Trait Implementations

impl Clone for EventStateChange

fn clone(&self) -> EventStateChange

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EventStateChange

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for EventStateChange

fn eq(&self, other: &EventStateChange) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
