Use Asyncer correctly in Python code that mixes async functions, blocking sync functions, worker threads, or concurrent async tasks. Use when choosing between Asyncer, AnyIO, and asyncio patterns; replacing asyncio.gather, AnyIO task groups, to_thread/from_thread calls, or anyio.run wrappers; using asyncer.create_task_group(), TaskGroup.soonify(), SoonValue, asyncify(), syncify(), or runnify(); or avoiding common Asyncer mistakes.
