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.

BacktestProjection

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

BacktestReport

Full replay output.

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.

Traits

BacktestModel

Product-supplied deterministic replay behavior.

Functions

run_backtest

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