Lightweight, an ODBC SQL API for C++23

Lightweight is a thin and modern C++ ODBC wrapper for easy and fast raw database access.

Goals

Easy to use - simple, expressive and intuitive API
Production ready - targeting production grade systems
Performance - do as little as possible, and as much as necessary - Zero overhead abstraction is a key design requirement.
Extensible - support for custom data types for writing to and reading from columns
Resource aware - efficient resource management and exception safety

Feature creeping (ODBC is a huge API, we are not going to wrap everything)
No intend to support non-ODBC connectors directly, in order to keep the codebase simple and focused

Customizable logging infrastructure with support for trace and performance timing logging
Flexible SQL dialect-agnostic query builder API
Support for custom data types

Only ODBC is supported, so it should work on any platform that has an ODBC driver and a modern enough C++ compiler.

This library a little bit of more modern C++ language and library features in order to be more expressive and efficient.

C++23 (std::stacktrace, lambda templates expressions)
C++20 (std::source_location, std::error_code, operator<=>, std::format(), designated initializers, concepts, ranges)
C++17 (fold expressions, std::string_view, std::optional, std::variant, std::apply)

You need to have the SQLite3 ODBC driver for SQLite installed.
