## 🚀 Quick Start
### Installation
```toml
[dependencies]
rust-logic-graph = "0.8.5"
# With specific integrations
rust-logic-graph = { version = "0.8.5", features = ["postgres", "openai"] }
# With all integrations
rust-logic-graph = { version = "0.8.5", features = ["all-integrations"] }
```
### Simple Example
```rust
use rust_logic_graph::{RuleEngine, GrlRule};
let grl = r#"
rule "Discount" {
when
cart_total > 100 && is_member == true
then
discount = 0.15;
}
"#;
let mut engine = RuleEngine::new();
engine.add_grl_rule(grl)?;
```
## 🏢 Real-World Case Study: Purchasing Flow System
See a complete production implementation in **[case_study/](case_study/)** - A full-featured purchasing automation system built with Rust Logic Graph.
### 📊 System Overview
**Problem**: Automate purchasing decisions for inventory replenishment across multiple products, warehouses, and suppliers.
**Solution**: Business rules in GRL decide when/how much to order. Orchestrator executes the workflows.
### 🎯 Two Architecture Implementations
**1. Microservices (v4.0)** - 7 services with gRPC
- Orchestrator (port 8080) - Workflow coordination
- OMS Service (port 50051) - Order management data
- Inventory Service (port 50052) - Stock levels
- Supplier Service (port 50053) - Supplier information
- UOM Service (port 50054) - Unit conversions
- Rule Engine (port 50055) - GRL business rules
- PO Service (port 50056) - Purchase order management
**2. Monolithic** - Single HTTP service
- Same business logic as microservices
- Single process on port 8080
- Shared GRL rules file
- Direct function calls instead of gRPC
### 🔥 GRL Business Rules (15 Rules)
```grl
rule "CalculateShortage" salience 120 no-loop {
when
required_qty > 0
then
Log("Calculating shortage...");
shortage = required_qty - available_qty;
Log("Shortage calculated");
}
rule "OrderMOQWhenShortageIsLess" salience 110 no-loop {
when
shortage > 0 && shortage < moq && is_active == true
then
Log("Shortage less than MOQ, ordering MOQ");
order_qty = moq;
}
```
**See full rules**: [purchasing_rules.grl](case_study/microservices/services/rule-engine-service/rules/purchasing_rules.grl)
### YAML Configuration (NEW in v0.8.5)
Both Monolithic and Microservices implementations now support **YAML-based graph configuration**:
```yaml
# purchasing_flow_graph.yaml
nodes:
oms_grpc:
type: DBNode
description: "Fetch order management data"
inventory_grpc:
type: DBNode
description: "Fetch inventory levels"
rule_engine_grpc:
type: RuleNode
description: "Evaluate business rules"
dependencies:
- oms_grpc
- inventory_grpc
edges:
- from: oms_grpc
to: rule_engine_grpc
- from: inventory_grpc
to: rule_engine_grpc
```
**Benefits:**
- ✅ **70% less code** - Graph definition moves from code to YAML
- ✅ **No recompile** - Change workflows without rebuilding
- ✅ **Multiple workflows** - Easy to create variants (urgent, standard, approval)
- ✅ **Better readability** - Clear, declarative graph structure
- ✅ **Easy testing** - Test with different configurations
**Usage:**
```rust
// Default config
executor.execute("PROD-001").await?;
// Custom workflow
executor.execute_with_config("PROD-001", "urgent_flow.yaml").await?;
```
**Documentation**: See [YAML_CONFIGURATION_SUMMARY.md](case_study/YAML_CONFIGURATION_SUMMARY.md)
### Microservices Communication Flow
After v0.8.0 refactor, the Orchestrator now uses **rust-logic-graph's Graph/Executor pattern** to coordinate microservices:
- The Orchestrator receives a purchasing request (HTTP) and creates a **Graph** with 6 custom **gRPC Nodes**.
- Each Node wraps a gRPC call to a service: `OmsGrpcNode`, `InventoryGrpcNode`, `SupplierGrpcNode`, `UomGrpcNode`, `RuleEngineGrpcNode`, `PoGrpcNode`.
- The **Executor** runs the graph in topological order:
1. **Data Collection Phase** (parallel): OMS, Inventory, Supplier, UOM nodes execute simultaneously via gRPC
2. **Rule Evaluation Phase**: RuleEngineGrpcNode waits for all data, then evaluates GRL rules
3. **Execution Phase**: PoGrpcNode creates/sends PO based on rule decisions
- All business logic (decision flags, calculations) comes from GRL rules. The Orchestrator is a pure executor.
**Graph Topology**:
```
OMS Node ────┐
│
Inventory ───┼──→ RuleEngine Node ──→ PO Node
│
Supplier ────┤
│
UOM Node ────┘
```
**Benefits of Graph/Executor Pattern**:
- ✅ **Declarative**: Define workflow as nodes + edges instead of imperative code
- ✅ **Parallel Execution**: Data nodes run concurrently automatically
- ✅ **Type Safety**: Custom Node implementations with Rust's type system
- ✅ **Testable**: Each node can be tested in isolation
- ✅ **Consistent**: Same pattern used in monolithic and microservices

```
**Note**: The Rule Engine service returns decision flags and calculations to the Graph Context. The PoGrpcNode then reads these flags from the context to determine whether to create/send the PO.
### Where rust-logic-graph is Used
**Monolithic App** (`case_study/monolithic/`):
- Uses `Graph`, `Executor`, and custom `Node` implementations
- 6 DB nodes query local MySQL databases directly
- `RuleEngineNode` calls in-process `RuleEngine`
- Single process, no network calls
**Orchestrator Microservice** (`case_study/microservices/services/orchestrator-service/`):
- Uses `Graph`, `Executor`, and custom gRPC `Node` implementations
- 6 gRPC nodes make network calls to remote services
- Same graph topology as monolithic
- Distributed across multiple processes
**Rule Engine Service** (`case_study/microservices/services/rule-engine-service/`):
- Uses `RuleEngine` for GRL evaluation
- Exposed via gRPC endpoint
- Stateless service (no graph execution)
**Other Microservices** (OMS, Inventory, Supplier, UOM, PO):
- Standard gRPC services with database access
- Do NOT use rust-logic-graph directly
- Called by Orchestrator's Graph Executor
