Припустимо, що тепер файл `main.py` із Вашим **FastAPI**-застосунком містить додаткові операції шляху (**path operations**).

Він має `GET`-операцію, яка може повертати помилку.

Він має `POST`-операцію, яка може повертати кілька помилок.

Обидві операції шляху вимагають заголовок `X-Token`.

  // Socket writes are guarded by frameWriter.

  // Socket reads are unguarded but are only made by the reader thread.

  // Certain operations (like SYN_STREAM) need to synchronize on both the frameWriter (to do
  // blocking I/O) and this (to create streams). Such operations must synchronize on 'this' last.
