cpp-pubsub

cpp-pubsub is a fast, header-only C++ library for thread-safe Publish/Subscribe messaging. It is designed to be lightweight and simple to integrate into any modern C++17 codebase.

Key Features

Thread-Safe by Design: Safe multi-threaded dispatching with standard C++ primitives ensures publishers and subscribers can interact without data races.
Robust Memory Management: Built from the ground up to respect C++ smart pointers (std::shared_ptr). Zero-leak guarantees even when unread messages are dropped from full queues, and automatic cleanup of disconnected subscribers.
Background Workers: OS-level events power high-performance background multiplexing for advanced systems.
