Struct InMemoryLedger 

pub struct InMemoryLedger { /* private fields */ }

A CostLedger that keeps every record in memory, oldest first. Process-local — one isolate’s view on Workers — which suits a measurement window and is not a billing system.

Implementations

impl InMemoryLedger

pub fn new() -> Self

An empty ledger.

pub fn records(&self) -> Vec<CallRecord>

Every record so far, oldest first.

pub fn totals(&self) -> BTreeMap<AdapterId, LedgerTotals>

Totals per adapter.

pub fn role_totals(&self) -> BTreeMap<CallRole, LedgerTotals>

Totals per CallRole: the Discarded row is what escalation wasted, the Shadow row what measuring cost.
