Struct TimelineRow 

pub struct TimelineRow {
    pub key: String,
    pub lane: LaneId,
    pub t_us: u64,
    pub hlc: Option<HlcStamp>,
    pub source: Option<String>,
    pub sn: Option<u32>,
    pub kind: RowKind,
    pub payload_bytes: usize,
}

One sample, reduced to what a timeline needs: where it sits on each axis, which lane it belongs to, and what it was. No payload — the timeline is about when, and a pane that wants the bytes has the retained window.

Fields

key: String

lane: LaneId

t_us: u64

Arrival, µs since the window epoch (the observer’s monotonic clock).

hlc: Option<HlcStamp>

None exactly when the lane is LaneId::Unstamped.

source: Option<String>

The publishing entity, zid:eid, when SourceInfo rode the sample.

sn: Option<u32>

That entity’s sequence number for this sample.

kind: RowKind

payload_bytes: usize

Implementations

impl TimelineRow

pub fn from_view(view: &SampleView, epoch: Instant, base: &str) -> TimelineRow

A row from a live sample, t_us measured from epoch — the instant the caller’s watches were all declared. A sample received before the epoch saturates to 0, as ZrecWriter does.
