LatencyReport

Struct LatencyReport 

Source
pub struct LatencyReport {
    pub self_stamped: Option<LatencySummary>,
    pub foreign: Option<LatencySummary>,
    pub unattributable: Option<LatencySummary>,
    pub stampers: Vec<String>,
    pub stampers_dropped: u64,
}
Expand description

One key’s observed latency, kept apart by who stamped it (issue #213).

Three populations, never folded into one median. A publisher-stamped sample measures publisher → observer; a router-stamped one measures that router → observer, which is a different quantity on the same axis. Averaging them produces a number that describes neither, and a fleet where some producers timestamp and some do not would report it without a word.

Fields§

§self_stamped: Option<LatencySummary>

Samples the publishing session stamped itself.

§foreign: Option<LatencySummary>

Samples stamped by another node — commonly a router.

§unattributable: Option<LatencySummary>

Stamped, but with no SourceInfo to compare against: unknown, not foreign (RFC 09 §5.1 O4).

§stampers: Vec<String>

The distinct stamping nodes seen on this key, rendered. Empty when every sample was self-stamped — there is no third party to name.

§stampers_dropped: u64

Stampers beyond the retained bound that were dropped (O6: a bound reports what it cost).

Implementations§

Source§

impl LatencyReport

Source

pub fn is_empty(&self) -> bool

Whether anything was observed at all.

Source

pub fn populations(&self) -> Vec<(&'static str, LatencySummary)>

The populations present, each with the label that says what it measures. Ordered self → foreign → unattributable.

Source

pub fn caveat(&self) -> String

The caveat that has to travel with every rendering of these numbers.

One sentence, in the engine, so the CLI and the GUI cannot drift into describing the same measurement differently (RFC 09 §5.1 O7).
