null.py¶

Generated: 2026-03-30T04:38:46.136784+00:00

Commit: 615f1354a103

Language: python

Scope: dazzle_back

Purpose¶

No-op event system implementations.

Provides NullBus and NullEventFramework for use when the full event system dependencies (psycopg, etc.) are not installed. These implementations silently accept all operations, allowing application code to use the event API without conditional checks.
