Muonroi.RuleEngine.Core

NuGet

Core execution orchestrator for the Muonroi Rule Engine, providing rule evaluation, dependency resolution, and FactBag state management.

Installation

dotnet add package Muonroi.RuleEngine.Core

Overview

The core orchestration layer for executing rule pipelines. It defines RuleOrchestrator<TContext> which implements IMRuleOrchestrator<TContext> to evaluate sequences of IRule<TContext>. State transitions between rules are managed via the FactBag, and each rule returns a RuleResult determining execution flow based on the current ExecutionMode (e.g. AllOrNothing, BestEffort).

Features

  • Engine Configuration: MRuleEngineBuilder for fluent setup of execution options and dependencies.
  • Rule Definitions: IRule<TContext> for defining atomic pieces of logic, with properties for Code, Order, DependsOn, and HookPoint.
  • State Management: FactBag for strongly typed state passing between rules via Get<T>() and Set<T>().
  • Execution Orchestration: IMRuleOrchestrator<TContext> and RuleOrchestrator<TContext> to execute rule chains and aggregate an OrchestratorResult.
  • Execution Modes: Configure behavior on failure via the ExecutionMode enum (AllOrNothing, BestEffort, CompensateOnFailure).

Quick Start

// Configure engine dependencies and defaults
builder.Services.AddRuleEngine<OrderContext>(options =>
{
    options.Mode = ExecutionMode.BestEffort;
});

// Resolve the orchestrator and execute
var orchestrator = provider.GetRequiredService<IMRuleOrchestrator<OrderContext>>();
var result = await orchestrator.ExecuteAsync(new OrderContext(), cancellationToken);

Ecosystem Combinations

+ Mediator → Rules Run Before Every Command

MRuleEngineBehavior in the mediator pipeline calls IMRuleOrchestrator.ExecuteAsync() before the handler. Business rules become hot-reloadable without touching handler code:

public class PlaceOrderCommand : IRequest<OrderDto>, IMRuleRequest
{
    public string RuleContext => "ORDER_PLACEMENT";
}
// Handler is pure — rules evaluated by the pipeline, not the handler

+ Tenancy.Core → Per-Tenant Rule Quotas

ITenantQuotaTracker gates how many rule evaluations a tenant can execute per time window. Free tier: 1,000/day. Enterprise: unlimited.

+ Observability → Per-Rule OTel Spans

Every IRule<TContext>.EvaluateAsync() call becomes an OTel span via IRuleExecutionTracer. Diagnose slow rules in Grafana.
