libnetwrk

Header-only cross-platform networking library.

About

Based on javidx9's work with networking.
Recommended for use on small personal projects as it's not heavily tested.

Dependencies

• ASIO 1.30.2 (embedded)

Requirements

• c++20
• compiler support for concepts and coroutines

Tested compiler support

• MSVC 14.30 / Visual Studio 2022 17.0
• GCC 10.5 with -fconcepts and -fcoroutines

Usage

CMake

libnetwrk TARGET is provided as an INTERFACE that sets up compile flags, definitions and include directories.

• Add libnetwrk via ADD_SUBDIRECTORY or FetchContent
• Use LINK_LIBRARIES(libnetwrk) or TARGET_LINK_LIBRARIES(your_target PRIVATE|PUBLIC libnetwrk)
• Include libnetwrk.hpp

Limitations

• currently only supports TCP
• std::size_t clamped to uint32_t to enable architecture independent serialization/deserialization of STL containers

Usage examples

Making a custom object serializeable

void serialize(libnetwrk::dynamic_buffer& buffer) const {
    ...
}

void deserialize(libnetwrk::dynamic_buffer& buffer) {
    ...
}

To make an object serializable you need to add and implement these functions.

#include "libnetwrk.hpp"

struct object {
    std::string string_1;
  
    void serialize(libnetwrk::dynamic_buffer& buffer) const {
        buffer << string_1;
    }
  
    void deserialize(libnetwrk::dynamic_buffer& buffer) {
        buffer >> string_1;
    }
}

struct derived_object : object {
    std::string string_2;
  
    void serialize(libnetwrk::dynamic_buffer& buffer) const {
        object::serialize(buffer);
        buffer << string_2;
    }
  
    void deserialize(libnetwrk::dynamic_buffer& buffer) {
        object::deserialize(buffer);
        buffer >> string_2;
    }
}
