Struct BusMetadata 

pub struct BusMetadata {
    pub codec: u8,
    pub producer: ProducerId,
    pub sequence: u64,
    pub produced_at: Option<TimeWindow>,
    pub participant: String,
}

Per-sample metadata carried in the Zenoh attachment (MessagePack-encoded).

Fields

codec: u8

The codec used for the body payload.

producer: ProducerId

The producing process.

sequence: u64

This producer’s monotonically increasing sample sequence, starting at zero for every fresh process.

produced_at: Option<TimeWindow>

When this sample’s content was produced in robot time, if it expresses robot time at all. Commands and diagnostics carry None.

participant: String

The producing participant id - a diagnostic label only (never identity, never an admissibility input).

Implementations

impl BusMetadata

pub fn encode(&self) -> Vec<u8>

Encode to the MessagePack attachment bytes.

pub fn decode(bytes: &[u8]) -> Result<BusMetadata, Error>

Decode from the MessagePack attachment bytes.

pub fn codec_id(&self) -> Option<CodecId>

The codec id, if recognized by this wire ABI.

pub fn produced_exactly_at(&self) -> Option<RobotInstant>

The production instant when it is exactly known.

A state sample published at a logical step is exact; a measurement translated from a device clock generally is not, and a consumer that needs an exact instant from one has to say so.
