🐛 Fixed `bootstrap_streaming` support for `CQRSContainer`

Release Notes - Version 4.6.1

🐛 Bug Fixes

Fixed bootstrap_streaming support for CQRSContainer

Issue: The bootstrap_streaming method did not support CQRSContainer (like DependencyInjectorCQRSContainer), unlike other bootstrap methods (bootstrap for requests, events, and sagas). This caused errors when trying to use DependencyInjectorCQRSContainer with streaming mediators:

'DependencyInjectorCQRSContainer' object has no attribute 'solve'

Fix:

• Added CQRSContainer support to bootstrap_streaming method, following the same pattern as other bootstrap methods
• Updated setup_streaming_mediator to accept both DIContainer and CQRSContainer types
• Added proper type overloads for better type checking
• The method now correctly handles both di.Container and CQRSContainer instances:
  • If di.Container is provided, it wraps it in DIContainer()
  • If CQRSContainer is provided, it uses it directly

Impact: Users can now use DependencyInjectorCQRSContainer and other CQRSContainer implementations with bootstrap_streaming, enabling dependency injection integration with streaming request handlers.

✅ Testing

• Added comprehensive test suite for bootstrap_streaming with DependencyInjectorCQRSContainer
• Tests cover:
  • Basic streaming functionality with dependency injection
  • Event processing with dependency injection
  • Parallel event handling with dependency injection
  • Interface-based dependency resolution

📝 Technical Details

Files Changed:

• src/cqrs/requests/bootstrap.py: Added CQRSContainer support to bootstrap_streaming and setup_streaming_mediator

New Files:

• tests/unit/test_bootstrap_streaming_dependency_injector.py: Comprehensive test suite for the new functionality

🔄 Migration Guide

No migration required. This is a backward-compatible bug fix. Existing code using di.Container will continue to work as before. Code using CQRSContainer with bootstrap_streaming will now work correctly.
