Struct ReportBuilder 

pub struct ReportBuilder { /* private fields */ }

Accumulates a Report one record at a time, holding pricing samples, one accumulator per trade direction, and the venue labels seen — never the records.

Every price is a median over the whole stream, so amounts accumulate raw and convert once in ReportBuilder::finish. Prices::usd is linear in the amount, which is what makes that identical to converting each hop as it arrives.

Implementations

impl ReportBuilder

pub fn new(target: Target) -> Self

pub fn push(&mut self, record: &LegRecord)

Take one record’s contribution. Cheap and order-independent.

pub fn finish(self) -> Result<Report, RerouteReportError>

Nothing matched on either side means the selector named something the stream never saw.
