C# Stateless Parity

stateless-py is inspired by C# Stateless and implements most core concepts with Pythonic API conventions.

Implemented Concepts

• Fluent state configuration
• Fixed, guarded, ignored, reentry, internal, and dynamic transitions
• Hierarchical states with initial substate support
• Entry/exit/activate/deactivate actions
• Async guards/actions/selectors with fire_async
• Introspection and graph export
• Immediate and queued firing modes

Python-Specific Differences

• Trigger payloads are passed directly via fire(..., *args)
• Trigger parameter metadata (set_trigger_parameters) is introspection-oriented
• Transition callbacks are configured at StateMachine construction
• Async behavior is managed with asyncio

Practical Guidance

Use the API as idiomatic Python rather than expecting one-to-one method names from C#.
