Struct TraceRow 

pub struct TraceRow {
    pub key: String,
    pub relation: TraceRelation,
    pub arrival_delta_ms: f64,
    pub hlc: Option<String>,
    pub hlc_delta_ms: Option<i64>,
    pub stamped_by: Option<String>,
    pub kind: RowKind,
    pub payload_bytes: usize,
    pub break_before: Option<u64>,
}

One sample observed on the called origin after the call.

Fields

key: String

relation: TraceRelation

arrival_delta_ms: f64

Arrival on this observer’s monotonic clock, ms since t0 — the instant after the watches were declared and before the GET left. Always present.

hlc: Option<String>

The sample’s HLC, <ntp64>/<stamper>, when it carried one.

hlc_delta_ms: Option<i64>

Sample HLC minus the reply’s HLC, ms — present only when both exist. Signed: a negative value is a sample stamped before the reply on the stamper’s clock, which is a fact to show, not to clamp.

stamped_by: Option<String>

Who stamped hlc: self, foreign:<id> or unattributable:<id> (RFC 09 §5.1 O7). Present exactly when hlc is.

kind: RowKind

payload_bytes: usize

break_before: Option<u64>

Samples this observer missed while behind, between the previous row of this lane and this one (O6). A break rides the row that follows it in every lane, because the broadcast does not know whose samples it lost.
