Struct SegmentReceiver 

pub struct SegmentReceiver { /* private fields */ }

Collects received segments for reassembly.

Segments can arrive out of order. Call reassemble once all segments have been received.

Implementations

impl SegmentReceiver

pub fn new() -> Self

Create a new empty receiver.

pub fn receive(&mut self, sequence_number: u8, data: Bytes) -> Result<(), Error>

Store a received segment.

Returns an error if the segment exceeds MAX_SEGMENT_SIZE.

pub fn has_segment(&self, sequence_number: u8) -> bool

Check whether a specific segment has been received.

pub fn received_count(&self) -> usize

Number of segments received so far.

pub fn reassemble(&self, total_segments: usize) -> Result<Vec<u8>, Error>

Reassemble all segments in order. total_segments is the expected count.

Returns an error if any segment is missing or if total_segments exceeds the BACnet 8-bit sequence number limit (256).

Trait Implementations

impl Default for SegmentReceiver

fn default() -> Self

Returns the “default value” for a type.
