Struct MeasuredJoin 

pub struct MeasuredJoin { /* private fields */ }

PP-3 / PP-22 / P-5 — a comparator lane that passed the join, and the ratios it produced.

Why the fields are private

While ComparatorStatus::Measured was a struct variant with public fields, any caller could write

ComparatorStatus::Measured { baseline: Box::new(band), ratios }

and attach a baseline from another run, another band, or a lane that timed out — the three things BandInput::join_status_in exists to refuse. The refusals lived in a function nothing forced anyone to call. Wrapping the payload in a type whose only constructor is pub(crate) and which is reachable only from that function makes the refusals structural: outside aprender-test-lib there is no expression that produces one.

Reading is unrestricted — Self::baseline and Self::ratios — because a receipt renderer must be able to see what it is rendering.

Implementations

impl MeasuredJoin

pub fn baseline(&self) -> &DerivedBand

The comparator lane’s band.

pub fn ratios(&self) -> &BandRatios

P-5 — the ratios formed against that band.
