# HeroModels Rhai Engine (`engine`)
|
||||
|
||||
The `engine` crate provides a central Rhai scripting engine for the HeroModels project. It offers a unified way to interact with various HeroModels modules (like Calendar, Flow, Legal, etc.) through Rhai scripts, leveraging a shared database connection.
|
||||
|
||||
## Overview
|
||||
|
||||
This crate facilitates:
|
||||
|
||||
1. **Centralized Engine Creation**: A function `create_heromodels_engine` to instantiate a Rhai engine pre-configured with common settings and all enabled HeroModels modules.
|
||||
2. **Modular Registration**: HeroModels modules (Calendar, Flow, etc.) can be registered with a Rhai engine based on feature flags.
|
||||
3. **Script Evaluation Utilities**: Helper functions for compiling Rhai scripts into Abstract Syntax Trees (ASTs) and for evaluating scripts or ASTs.
|
||||
4. **Mock Database**: Includes a `mock_db` module for testing and running examples without needing a live database.
|
||||
|
||||
## Core Components & Usage
|
||||
|
||||
### Library (`src/lib.rs`)
|
||||
|
||||
- **`create_heromodels_engine(db: Arc<OurDB>) -> Engine`**:
|
||||
Creates and returns a new `rhai::Engine` instance. This engine is configured with default settings (e.g., max expression depths, string/array/map sizes) and then all available HeroModels modules (controlled by feature flags) are registered with it, using the provided `db` (an `Arc<OurDB>`) instance.
|
||||
|
||||
- **`register_all_modules(engine: &mut Engine, db: Arc<OurDB>)`**:
|
||||
Registers all HeroModels modules for which features are enabled (e.g., `calendar`, `flow`, `legal`, `projects`, `biz`) with the given Rhai `engine`. Each module is passed the shared `db` instance.
|
||||
|
||||
- **`eval_script(engine: &Engine, script: &str) -> Result<rhai::Dynamic, Box<rhai::EvalAltResult>>`**:
|
||||
A utility function to directly evaluate a Rhai script string using the provided `engine`.
|
||||
|
||||
- **`compile_script(engine: &Engine, script: &str) -> Result<AST, Box<rhai::EvalAltResult>>`**:
|
||||
Compiles a Rhai script string into an `AST` (Abstract Syntax Tree) for potentially faster repeated execution.
|
||||
|
||||
- **`run_ast(engine: &Engine, ast: &AST, scope: &mut Scope) -> Result<rhai::Dynamic, Box<rhai::EvalAltResult>>`**:
|
||||
Runs a pre-compiled `AST` with a given `scope` using the provided `engine`.
|
||||
|
||||
- **`mock_db` module**:
|
||||
Provides `create_mock_db()` which returns an `Arc<OurDB>` instance suitable for testing and examples. This allows scripts that interact with database functionalities to run without external database dependencies.
|
||||
|
||||
### Basic Usage
|
||||
|
||||
```rust
|
||||
use std::sync::Arc;
|
||||
use engine::{create_heromodels_engine, eval_script};
|
||||
use engine::mock_db::create_mock_db; // For example usage
|
||||
use heromodels::db::hero::OurDB; // Actual DB type
|
||||
|
||||
// Create a mock database (or connect to a real one)
|
||||
let db: Arc<OurDB> = create_mock_db();
|
||||
|
||||
// Create the Rhai engine with all enabled modules registered
|
||||
let engine = create_heromodels_engine(db);
|
||||
|
||||
// Run a Rhai script
|
||||
let script = r#"
|
||||
// Example: Assuming 'calendar' feature is enabled
|
||||
let cal = new_calendar("My Test Calendar");
|
||||
cal.set_description("This is a test.");
|
||||
print(`Created calendar: ${cal.get_name()}`);
|
||||
cal.get_id() // Return the ID
|
||||
"#;
|
||||
|
||||
match eval_script(&engine, script) {
|
||||
Ok(val) => println!("Script returned: {:?}", val),
|
||||
Err(err) => eprintln!("Script error: {}", err),
|
||||
}
|
||||
```
|
||||
|
||||
### Using Specific Modules Manually
|
||||
|
||||
If you need more fine-grained control or only want specific modules (and prefer not to rely solely on feature flags at compile time for `create_heromodels_engine`), you can initialize an engine and register modules manually:
|
||||
|
||||
```rust
|
||||
use std::sync::Arc;
|
||||
use rhai::Engine;
|
||||
use engine::mock_db::create_mock_db; // For example usage
|
||||
use heromodels::db::hero::OurDB;
|
||||
// Import the specific module registration function
|
||||
use heromodels::models::calendar::register_calendar_rhai_module;
|
||||
|
||||
|
||||
// Create a mock database
|
||||
let db: Arc<OurDB> = create_mock_db();
|
||||
|
||||
// Create a new Rhai engine
|
||||
let mut engine = Engine::new();
|
||||
|
||||
// Register only the calendar module
|
||||
register_calendar_rhai_module(&mut engine, db.clone());
|
||||
|
||||
// Now you can use calendar-related functions in your scripts
|
||||
let result = engine.eval::<String>(r#" let c = new_calendar("Solo Cal"); c.get_name() "#);
|
||||
match result {
|
||||
Ok(name) => println!("Calendar name: {}", name),
|
||||
Err(err) => eprintln!("Error: {}", err),
|
||||
}
|
||||
```
|
||||
|
||||
## Examples
|
||||
|
||||
This crate includes several examples demonstrating how to use different HeroModels modules with Rhai. Each example typically requires its corresponding feature to be enabled.
|
||||
|
||||
- `calendar_example`: Working with calendars, events, and attendees (requires `calendar` feature).
|
||||
- `flow_example`: Working with flows, steps, and signature requirements (requires `flow` feature).
|
||||
- `finance_example`: Working with financial models (requires `finance` feature).
|
||||
- *(Additional examples for `legal`, `projects`, `biz` would follow the same pattern if present).*
|
||||
|
||||
To run an example (e.g., `calendar_example`):
|
||||
|
||||
```bash
|
||||
cargo run --example calendar_example --features calendar
|
||||
```
|
||||
*(Note: Examples in `Cargo.toml` already specify `required-features`, so simply `cargo run --example calendar_example` might suffice if those features are part of the default set or already enabled.)*
|
||||
|
||||
## Features
|
||||
|
||||
The crate uses feature flags to control which HeroModels modules are compiled and registered:
|
||||
|
||||
- `calendar`: Enables the Calendar module.
|
||||
- `finance`: Enables the Finance module.
|
||||
- `flow`: Enables the Flow module.
|
||||
- `legal`: Enables the Legal module.
|
||||
- `projects`: Enables the Projects module.
|
||||
- `biz`: Enables the Business module.
|
||||
|
||||
The `default` features are `["calendar", "finance"]`. You can enable other modules by specifying them during the build or in your project's `Cargo.toml` if this `engine` crate is a dependency.
|
||||
|
||||
## Dependencies
|
||||
|
||||
Key dependencies include:
|
||||
- `rhai`: The Rhai scripting engine.
|
||||
- `heromodels`: Provides the core data models and database interaction logic, including the Rhai registration functions for each module.
|
||||
- `heromodels_core`: Core utilities for HeroModels.
|
||||
- `chrono`: For date/time utilities.
|
||||
- `heromodels-derive`: Procedural macros used by HeroModels.
|
||||
|
||||

# Architecture of the `rhailib_engine` Crate
|
||||
|
||||
The `rhailib_engine` crate serves as the central Rhai scripting engine for the heromodels ecosystem. It provides a unified interface for creating, configuring, and executing Rhai scripts with access to all business domain modules through a feature-based architecture.
|
||||
|
||||
## Core Architecture
|
||||
|
||||
The engine acts as an orchestration layer that brings together the DSL modules and provides execution utilities:
|
||||
|
||||
```mermaid
|
||||

|
||||
|
||||
D --> D1[create_mock_db]
|
||||
D --> D2[seed_mock_db]
|
||||
D --> D3[Domain Data Seeding]
|
||||
|
||||
E --> E1[calendar]
|
||||
E --> E2[finance]
|
||||
E --> E3[flow]
|
||||
E --> E4[legal]
|
||||
E --> E5[projects]
|
||||
E --> E6[biz]
|
||||
|
||||
B3 --> F[rhailib_dsl]
|
||||
F --> G[All Domain Modules]
|
||||
```
|
||||
|
||||
## Core Components
|
||||
|
||||
### 1. Engine Factory (`create_heromodels_engine`)
|
||||
|
||||
The primary entry point for creating a fully configured Rhai engine:
|
||||
|
||||
```rust
|
||||
pub fn create_heromodels_engine() -> Engine
|
||||
```
|
||||
|
||||
**Responsibilities:**
|
||||
- Creates a new Rhai engine instance
|
||||
- Configures engine limits and settings
|
||||
- Registers all available DSL modules
|
||||
- Returns a ready-to-use engine
|
||||
|
||||
**Configuration Settings:**
|
||||
- **Expression Depth**: 128 levels for both expressions and functions
|
||||
- **String Size Limit**: 10 MB maximum string size
|
||||
- **Array Size Limit**: 10,000 elements maximum
|
||||
- **Map Size Limit**: 10,000 key-value pairs maximum
|
||||
|
||||
### 2. Script Execution Utilities
|
||||
|
||||
#### Direct Script Evaluation
|
||||
```rust
|
||||
pub fn eval_script(engine: &Engine, script: &str) -> Result<Dynamic, Box<EvalAltResult>>
|
||||
```
|
||||
Executes Rhai script strings directly with immediate results.
|
||||
|
||||
#### File-Based Script Execution
|
||||
```rust
|
||||
pub fn eval_file(engine: &Engine, file_path: &Path) -> Result<Dynamic, Box<EvalAltResult>>
|
||||
```
|
||||
Loads and executes Rhai scripts from filesystem with proper error handling.
|
||||
|
||||
#### Compiled Script Execution
|
||||
```rust
|
||||
pub fn compile_script(engine: &Engine, script: &str) -> Result<AST, Box<EvalAltResult>>
|
||||
pub fn run_ast(engine: &Engine, ast: &AST, scope: &mut Scope) -> Result<Dynamic, Box<EvalAltResult>>
|
||||
```
|
||||
Provides compilation and execution of scripts for performance optimization.
|
||||
|
||||
### 3. Mock Database System
|
||||
|
||||
#### Database Creation
|
||||
```rust
|
||||
pub fn create_mock_db() -> Arc<OurDB>
|
||||
```
|
||||
Creates an in-memory database instance for testing and examples.
|
||||
|
||||
#### Data Seeding
|
||||
```rust
|
||||
pub fn seed_mock_db(db: Arc<OurDB>)
|
||||
```
|
||||
Populates the mock database with representative data across all domains.
|
||||
|
||||
## Feature-Based Architecture
|
||||
|
||||
The engine uses Cargo features to control which domain modules are included:
|
||||
|
||||
### Available Features
|
||||
|
||||
- **`calendar`** (default): Calendar and event management
|
||||
- **`finance`** (default): Financial accounts, assets, and marketplace
|
||||
- **`flow`**: Workflow and approval processes
|
||||
- **`legal`**: Contract and legal document management
|
||||
- **`projects`**: Project and task management
|
||||
- **`biz`**: Business operations and entities
|
||||
|
||||
### Feature Integration Pattern
|
||||
|
||||
```rust
|
||||
#[cfg(feature = "calendar")]
|
||||
use heromodels::models::calendar::*;
|
||||
|
||||
#[cfg(feature = "finance")]
|
||||
use heromodels::models::finance::*;
|
||||
```
|
||||
|
||||
This allows for:
|
||||
- **Selective Compilation**: Only include needed functionality
|
||||
- **Reduced Binary Size**: Exclude unused domain modules
|
||||
- **Modular Deployment**: Different configurations for different use cases
|
||||
|
||||
## Mock Database Architecture
|
||||
|
||||
### Database Structure
|
||||
|
||||
The mock database provides a complete testing environment:
|
||||
|
||||
```mermaid
|
||||
graph LR
|
||||
A[Mock Database] --> B[Calendar Data]
|
||||
A --> C[Finance Data]
|
||||
A --> D[Flow Data]
|
||||
A --> E[Legal Data]
|
||||
A --> F[Projects Data]
|
||||
|
||||
B --> B1[Calendars]
|
||||
B --> B2[Events]
|
||||
B --> B3[Attendees]
|
||||
|
||||
C --> C1[Accounts]
|
||||
C --> C2[Assets - ERC20/ERC721]
|
||||
C --> C3[Marketplace Listings]
|
||||
|
||||
D --> D1[Flows]
|
||||
D --> D2[Flow Steps]
|
||||
D --> D3[Signature Requirements]
|
||||
|
||||
E --> E1[Contracts]
|
||||
E --> E2[Contract Revisions]
|
||||
E --> E3[Contract Signers]
|
||||
|
||||
F --> F1[Projects]
|
||||
F --> F2[Project Members]
|
||||
F --> F3[Project Tags]
|
||||
```
|
||||
|
||||
### Seeding Strategy
|
||||
|
||||
Each domain has its own seeding function that creates realistic test data:
|
||||
|
||||
#### Calendar Seeding
|
||||
- Creates work calendars with descriptions
|
||||
- Adds team meetings with attendees
|
||||
- Sets up recurring events
|
||||
|
||||
#### Finance Seeding
|
||||
- Creates demo trading accounts
|
||||
- Generates ERC20 tokens and ERC721 NFTs
|
||||
- Sets up marketplace listings with metadata
|
||||
|
||||
#### Flow Seeding (Feature-Gated)
|
||||
- Creates document approval workflows
|
||||
- Defines multi-step approval processes
|
||||
- Sets up signature requirements
|
||||
|
||||
#### Legal Seeding (Feature-Gated)
|
||||
- Creates service agreements
|
||||
- Adds contract revisions and versions
|
||||
- Defines contract signers and roles
|
||||
|
||||
#### Projects Seeding (Feature-Gated)
|
||||
- Creates project instances with status tracking
|
||||
- Assigns team members and priorities
|
||||
- Adds project tags and categorization
|
||||
|
||||
## Error Handling Architecture
|
||||
|
||||
### Comprehensive Error Propagation
|
||||
|
||||
```rust
|
||||
Result<Dynamic, Box<EvalAltResult>>
|
||||
```
|
||||
|
||||
All functions return proper Rhai error types that include:
|
||||
- **Script Compilation Errors**: Syntax and parsing issues
|
||||
- **Runtime Errors**: Execution failures and exceptions
|
||||
- **File System Errors**: File reading and path resolution issues
|
||||
- **Database Errors**: Mock database operation failures
|
||||
|
||||
### Error Context Enhancement
|
||||
|
||||
File operations include enhanced error context:
|
||||
```rust
|
||||
Err(Box::new(EvalAltResult::ErrorSystem(
|
||||
format!("Failed to read script file: {}", file_path.display()),
|
||||
Box::new(io_err),
|
||||
)))
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Engine Configuration
|
||||
|
||||
Optimized settings for production use:
|
||||
- **Memory Limits**: Prevent runaway script execution
|
||||
- **Depth Limits**: Avoid stack overflow from deep recursion
|
||||
- **Size Limits**: Control memory usage for large data structures
|
||||
|
||||
### Compilation Strategy
|
||||
|
||||
- **AST Caching**: Compile once, execute multiple times
|
||||
- **Scope Management**: Efficient variable scope handling
|
||||
- **Module Registration**: One-time registration at engine creation
|
||||
|
||||
### Mock Database Performance
|
||||
|
||||
- **In-Memory Storage**: Fast access for testing scenarios
|
||||
- **Temporary Directories**: Automatic cleanup after use
|
||||
- **Lazy Loading**: Data seeded only when needed
|
||||
|
||||
## Integration Patterns
|
||||
|
||||
### Script Development Workflow
|
||||
|
||||
```rust
|
||||
// 1. Create engine with all modules
|
||||
let engine = create_heromodels_engine();
|
||||
|
||||
// 2. Execute business logic scripts
|
||||
let result = eval_script(&engine, r#"
|
||||
let company = new_company()
|
||||
.name("Tech Startup")
|
||||
.business_type("startup");
|
||||
save_company(company)
|
||||
"#)?;
|
||||
|
||||
// 3. Handle results and errors
|
||||
match result {
|
||||
Ok(value) => println!("Success: {:?}", value),
|
||||
Err(error) => eprintln!("Error: {}", error),
|
||||
}
|
||||
```
|
||||
|
||||
### Testing Integration
|
||||
|
||||
```rust
|
||||
// 1. Create mock database
|
||||
let db = create_mock_db();
|
||||
seed_mock_db(db.clone());
|
||||
|
||||
// 2. Create engine
|
||||
let engine = create_heromodels_engine();
|
||||
|
||||
// 3. Test scripts against seeded data
|
||||
let script = r#"
|
||||
let calendars = list_calendars();
|
||||
calendars.len()
|
||||
"#;
|
||||
let count = eval_script(&engine, script)?;
|
||||
```
|
||||
|
||||
### File-Based Script Execution
|
||||
|
||||
```rust
|
||||
// Execute scripts from files
|
||||
let result = eval_file(&engine, Path::new("scripts/business_logic.rhai"))?;
|
||||
```
|
||||
|
||||

|

|
||||
## Security Considerations
|
||||
|
||||
### Script Execution Limits
|
||||
- **Resource Limits**: Prevent resource exhaustion attacks
|
||||
- **Execution Time**: Configurable timeouts for long-running scripts
|
||||
- **Memory Bounds**: Controlled memory allocation
|
||||
|
||||
### Database Access
|
||||
- **Mock Environment**: Safe testing without production data exposure
|
||||
- **Temporary Storage**: Automatic cleanup prevents data persistence
|
||||
- **Isolated Execution**: Each test run gets fresh database state
|
||||
|
||||
## Extensibility
|
||||
|
||||
### Adding New Domains
|
||||
1. Create new feature flag in `Cargo.toml`
|
||||
2. Add conditional imports for new models
|
||||
3. Implement seeding function for test data
|
||||
4. Register with DSL module system
|
||||
|
||||
### Custom Engine Configuration
|
||||
```rust
|
||||
let mut engine = Engine::new();
|
||||
// Custom configuration
|
||||
engine.set_max_expr_depths(256, 256);
|
||||
// Register specific modules
|
||||
rhailib_dsl::register_dsl_modules(&mut engine);
|
||||
```
|
||||
|
||||
This architecture provides a robust, feature-rich foundation for Rhai script execution while maintaining flexibility, performance, and security.

//! # Rhailib Engine
|
||||
//!
|
||||
//! The central Rhai scripting engine for the heromodels ecosystem. This crate provides
|
||||
//! a unified interface for creating, configuring, and executing Rhai scripts with access
|
||||
//! to all business domain modules.
|
||||
//!
|
||||
//! ## Features
|
||||
//!
|
||||
//! - **Unified Engine Creation**: Pre-configured Rhai engine with all DSL modules
|
||||
//! - **Script Execution Utilities**: Direct evaluation, file-based execution, and AST compilation
|
||||
//! - **Mock Database System**: Complete testing environment with seeded data
|
||||
//! - **Feature-Based Architecture**: Modular compilation based on required domains
|
||||
//!
|
||||
//! ## Quick Start
|
||||
//!
|
||||
//! ```rust
|
||||
//! use rhailib_engine::{create_heromodels_engine, eval_script};
|
||||
//!
|
||||
//! // Create a fully configured engine
|
||||
//! let engine = create_heromodels_engine();
|
||||
//!
|
||||
//! // Execute a business logic script
|
||||
//! let result = eval_script(&engine, r#"
|
||||
//! let company = new_company()
|
||||
//! .name("Acme Corp")
|
||||
//! .business_type("global");
|
||||
//! company.name
|
||||
//! "#)?;
|
||||
//!
|
||||
//! println!("Company name: {}", result.as_string().unwrap());
|
||||
//! ```
|
||||
//!
|
||||
//! ## Available Features
|
||||
//!
|
||||
//! - `calendar` (default): Calendar and event management
|
||||
//! - `finance` (default): Financial accounts, assets, and marketplace
|
||||
//! - `flow`: Workflow and approval processes
