Crate af_backtest 

af-backtest — deterministic historical replay for product adapters.

This crate owns the reusable mechanics only: ordered historical ingress, state transitions, decision traces, value curves, metrics, and bounded report projection. Domain event types, accounting, execution semantics, data providers, and concrete strategies stay in product/extension crates.

Structs

BacktestConfig

Replay limits.

BacktestDefinition

Tenant-owned deterministic replay definition.

BacktestProjection

A transport/chat-safe projection of a potentially large full report.

BacktestReport

Full replay output.

BacktestRun

Durable replay record; computation resumes from these snapshots, never a mutable definition.

BacktestSummary

Aggregate metrics for a replay.

ProjectionPolicy

Caps for projecting a report to chat or API consumers.

ReplayStep

Captured decision trace for one event.

ValuePoint

Value after one event.

Enums

BacktestError

Failure while validating input or replaying.

BacktestRunStatus

Durable replay lifecycle.

BacktestStoreError

Failure owned by the durable replay store.

Traits

BacktestModel

Product-supplied deterministic replay behavior.

BacktestStore

Durable persistence port for definitions, snapshots, runs and bounded reports.

Functions

run_backtest

Execute a deterministic replay. Events with the same timestamp are allowed and preserve input order; decreasing timestamps fail closed.

run_backtest_with_control

Execute a deterministic replay while observing cancellation and deadline between input events.
