Supervisor Examples - Summary

✅ Complete End-to-End Examples with OpenRPC Client

All examples now use the official hero-supervisor-openrpc-client library for type-safe, async communication with the supervisor.

What Was Updated:

1. OpenRPC Client Library (clients/openrpc/src/lib.rs)

   • Added JobRunResponse - Response from blocking job.run
   • Added JobStartResponse - Response from non-blocking job.start
   • Updated job_run() method - Now accepts timeout parameter
   • Updated job_start() method - Now accepts Job instead of job_id
   • Re-exports Job and JobBuilder from runner_rust

2. Simple E2E Example (examples/simple_e2e.rs)

   • Uses SupervisorClient from OpenRPC library
   • Clean, type-safe API calls
   • No manual JSON-RPC construction
   • Perfect for learning and testing

3. Full E2E Demo (examples/end_to_end_demo.rs)

   • Automated supervisor and runner spawning
   • Uses OpenRPC client throughout
   • Helper functions for common operations
   • Comprehensive test scenarios

Key Changes:

Before (Manual JSON-RPC):

let request = json!({
    "jsonrpc": "2.0",
    "method": "job.run",
    "params": [{
        "secret": secret,
        "job": job,
        "timeout": 30
    }],
    "id": 1
});
let response = http_client.post(url).json(&request).send().await?;

After (OpenRPC Client):

let response = client.job_run(secret, job, Some(30)).await?;
println!("Result: {:?}", response.result);

Client API:

Job Execution

use hero_supervisor_openrpc_client::{SupervisorClient, JobBuilder};

// Create client
let client = SupervisorClient::new("http://localhost:3030")?;

// Register runner
client.register_runner("admin_secret", "runner_name", "queue_name").await?;

// Run job (blocking - waits for result)
let response = client.job_run("admin_secret", job, Some(60)).await?;
// response.result contains the actual result

// Start job (non-blocking - returns immediately)
let response = client.job_start("admin_secret", job).await?;
// response.job_id for later polling

Response Types

// JobRunResponse (from job.run)
pub struct JobRunResponse {
    pub job_id: String,
    pub status: String,      // "completed"
    pub result: Option<String>,  // Actual result from runner
}

// JobStartResponse (from job.start)
pub struct JobStartResponse {
    pub job_id: String,
    pub status: String,      // "queued"
}

Examples Overview:

Example	Description	Use Case
simple_e2e.rs	Manual setup, step-by-step	Learning, testing
end_to_end_demo.rs	Automated, comprehensive	CI/CD, integration tests

Running the Examples:

Prerequisites:

# Terminal 1: Redis
redis-server

# Terminal 2: Supervisor
cargo run --bin hero-supervisor -- --redis-url redis://localhost:6379

# Terminal 3: Runner
cargo run --bin runner_osis -- test_runner --redis-url redis://localhost:6379

Run Simple Example:

# Terminal 4
RUST_LOG=info cargo run --example simple_e2e

Run Full Demo:

# Only needs Redis running (spawns supervisor and runner automatically)
RUST_LOG=info cargo run --example end_to_end_demo

Benefits of OpenRPC Client:

✅ Type Safety - Compile-time checking of requests/responses ✅ Async/Await - Native Rust async support ✅ Error Handling - Proper Result types with detailed errors ✅ Auto Serialization - No manual JSON construction ✅ Documentation - IntelliSense and type hints ✅ Maintainability - Single source of truth for API

Job Execution Modes:

Blocking (job.run):

• Client waits for result
• Uses queue_and_wait internally
• Returns actual result
• Best for: CRUD, queries, short jobs

Non-Blocking (job.start):

• Client returns immediately
• Job runs in background
• Returns job_id for polling
• Best for: Long jobs, batch processing

Files Modified:

• ✅ clients/openrpc/src/lib.rs - Updated client methods and response types
• ✅ examples/simple_e2e.rs - Refactored to use OpenRPC client
• ✅ examples/end_to_end_demo.rs - Refactored to use OpenRPC client
• ✅ examples/E2E_EXAMPLES.md - Updated documentation
• ✅ examples/EXAMPLES_SUMMARY.md - This file

Next Steps:

1. Add more examples - Specific use cases (batch jobs, error handling)
2. Job polling - Implement wait_for_job() helper
3. WASM support - Browser-based examples
4. Signature examples - Jobs with cryptographic signatures
