stl_allocator	C++	A std::allocator compatible fixed-block memory allocator for the C++ Standard Library.
pmr_allocator	C++	A C++ Polymorphic Memory Resource (PMR) fixed-block memory allocator.

Callbacks

Repository	Language	Description
MulticastCallback	C	Type-safe multicast callbacks in C.
C_AsyncCallback	C	Asynchronous callbacks in C.
AsyncCallback	C++	Asynchronous callbacks in C++.
DelegateMQ	C++	Invoke any callable synchronously or asynchronously using C++ delegates.

Communications

Repository	Language	Description
SimpleSocketProtocol	C	A C-language socket-based communication transport protocol for Windows, Linux, Arduino and embedded systems.
DelegateMQ	C++	Invoke any remote function located in a separate process or processor using C++ delegates.

Serialization

Repository	Language	Description
MessageSerialize	C++	C++ object binary serialize and deserialize.
