Migrate code base to C++26 #1257
Description
ITNOA
I think C++20 and C++26 introduces many useful features.
some useful features are
- Modules (for better performance and library exposure)
- Concepts (for better meta programming)
- Contracts (for robust coding)
- std::optionals (for more declarative options)
- std::variants (same as above)
- std::any (same as above)
- structured binding (for better API)
- std::span (for better performance)
- std::string_view (for better performance)
- std::expected (for better API)
- compile time reflection (for more smarter inference and also cleaner API)
So we need to redesign public API with C++26 native way, and migrate code base into more modern C++.
In another way, I suggest below tasks
- Migrate internal code base into C++26
- Add new public API for C++26
- Migrate current API to C++17 (in backward compatible way) (co-exist with more modern C++26 API)
