Dependencies (minimal by design)

The library is intentionally simple and has minimal dependencies:

• Core modules have no external dependencies beyond the C++ standard library and the OS APIs.
• Optional components:
  • io_uring support on Linux uses liburing (optional).
  • SSL/TLS uses OpenSSL (optional).
  • Other features (like WebSocket) are layered on top of the core building blocks.
