Now code me only :

4. Health Checking & Circuit Breaking

These modules monitor the backends managed by the registry. 14. src/health/checker.rs 15. src/health/tcp_check.rs 16. src/health/http_check.rs 17. src/health/circuit_breaker.rs 18. src/health/passive_monitor.rs 19. src/health/mod.rs

5. Protocol Handling

Specific implementations for HTTP/1, HTTP/2, and streaming protocols. 20. src/protocol/mod.rs 21. src/protocol/http1.rs 22. src/protocol/http2.rs 23. src/protocol/websocket.rs

6. The Proxy (Request Orchestration)

The "Glue" code that takes a request, asks the Balancer for a Backend, checks Health, uses the Pool, and handles Protocols. 24. src/proxy/upstream.rs 25. src/proxy/request.rs 26. src/proxy/response.rs 27. src/proxy/handler.rs 28. src/proxy/streaming.rs 29. src/proxy/mod.rs

Quick reminder : Don't omit any part of the code , use rust best pratices and put comments in necessary places to deeply explain the code , don't write any unsafe rust code . It is a code that is going to be used in production so be creative and careful. but write less comments I mean put only necessary comments. I want to be creative this time. I don't want to write comment about 'real production` , just implement that part instantly because it is a real world production project, I want you to write the code as real production code like a a senior rust developer .

CLI Integration

# Run with TUI
streamforge --config config/streamforge.yaml --tui

# Run headless (daemon mode)
streamforge --config config/streamforge.yaml

# TUI-only mode (connect to running instance)
streamforge tui --connect localhost:9090

Performance Considerations

  1. Event Rate Limiting: Aggregate high-frequency events (e.g., batch 1000 RequestReceived into single MetricUpdate)
  2. Render Throttling: Update UI at max 60 FPS, even if events arrive faster
  3. History Buffers: Use fixed-size ring buffers (e.g., last 1000 points) to prevent unbounded memory growth
  4. Lazy Rendering: Only render visible widgets/views
  5. Async UI Updates: Don't block core load balancer with UI rendering
  6. Sampling: For very high traffic (>100k RPS), sample events rather than processing all

Testing Strategy

  1. Component Tests: Test individual widgets with mock data
  2. Integration Tests: Test view transitions and state management
  3. Snapshot Tests: Capture UI output and compare against golden files
  4. Performance Tests: Ensure TUI can handle 100k+ events/sec without lag
  5. Accessibility: Test with screen readers and keyboard-only navigation
