Co-C++19

The Fastest Meta Programming Library

A versatile collection of compile time optimized tools for C++ programming.

Target Compilers

This library uses the latest C++ features available in GCC, Clang and Visual Studio 2019 and 2022. It compiles in "c++20" mode on all compilers.

Currently tested Compilers:

• Clang 12 to 15
• GCC 11, 12
• Visual Studio 2019 v16.11.x, 2022 v17.4.x

Contents

Co-Cpp19 contains a lot of sublibraries and is splitted into many small headers. This aims to enable the "pay only what you use policy" of C++ at compile time.

• cpp19 - compiler configuration (yours should be somewhat similar)
• array19 - static and dynamic arrays, slices
• meta19 - utilities, type, index and pack wrappers and operations
• coro19 - basic coroutine with generator support
• strong19 - named strong types with tags
• enum19 - inspectable enum definitions
• string19 - compiletime string, view and string rope
• tuple19 - faster to compile std::tuple replacement
• optional19 - continuable optional and packed optional
• variant19 - faster compile and runtime std::variant replacement
• partial19 - densly packed and heap managed tuple<optional<>>
• serialize19 - customizable binary serialisation and deserialisation

Work in progress libraries, with less tests:

• signal19 - fast signal and slot handling
• lookup19 - ordered dynamic array lookup container

Naming Schema

C++ uses a unified namespace between types, functions and constants. Therefore we use the following patterns.

• UpperCamelCasing for types
• lowerCamelCasing for functions
• UPPER_CASING for precompiler definitions
• lower_casing for constexpr constants, concepts and namespaces

Words and Phrases

• *Of - reflects something of a type
• *At - uses something at an index
• [v]From() - converts from arguments to v
• *Type* - indicates that the method is just a signature for usage with decltype()
