fmt

{fmt} is an open-source formatting library designed to provide a fast and type-safe alternative to traditional C stdio and C++ iostreams. It features a simple format API with support for C++20's std::format and C++23's std::print, allows for user-defined type extensibility, and offers high-performance string formatting capabilities, including Unicode support and compile-time error reporting. The library is characterized by its small code size, reliability through extensive testing, and user-friendly implementation, making it suitable for a wide range of formatting tasks in C++ applications.
