Structured Event_Parameters for an EventEnrollment object.

Models every algorithm alternative of the Clause 21 BACnetEventParameter CHOICE. A context tag the 2020 production doesn’t assign (a later addendum’s or a vendor’s) is preserved verbatim via BACnetEventParameter::Opaque, so values written by a remote client are never silently discarded.

The wire form is the full ASN.1 CHOICE framing of the Clause 21 production, produced by bacnet_encoding::constructed::encode_event_parameter / decode_event_parameter and carried in PropertyValue::ApplicationData. The PropertyValue::List form here (leading algorithm tag as PropertyValue::Unsigned; see BACnetEventParameter::encode and BACnetEventParameter::decode) is the LEGACY pre-framing layout, kept for compatibility with values written before the framing migration (#154).

Implementations

impl BACnetEventParameter

pub fn encode(&self) -> PropertyValue

Encode this parameter set as a flat PropertyValue::List.

The first element is the algorithm tag as PropertyValue::Unsigned, followed by the variant’s fields in declaration order. This is the LEGACY pre-framing layout (see #154); the wire form is the full ASN.1 framing from bacnet_encoding::constructed::encode_event_parameter. See Self::decode for the inverse.

pub fn decode(value: &PropertyValue) -> Result<Self, Error>

Decode a PropertyValue previously produced by Self::encode.

Returns Ok with the reconstructed parameter set, or a decoding Error when the value is not a List, is empty, or has an unrecognized/inconsistent shape. Opaque values round-trip unchanged.

impl BACnetEventParameter

pub fn tag(&self) -> u8

Return the algorithm tag for this alternative.

Trait Implementations

impl Clone for BACnetEventParameter

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BACnetEventParameter

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

Formats the value using the given formatter.

impl PartialEq for BACnetEventParameter

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