About:
Fmt is a modern, open-source formatting library for C++ that provides a fast and safe alternative to C's printf. It offers a clean API for text formatting with compile-time checks, extensive customization options, and high performance. The library serves as the foundation for std::format in C++20.
Key Features:
  • Fast and type-safe formatting
  • Compile-time format string checks
  • Extensive customization options
  • Lightweight with no dependencies
  • Standardized as C++20 std::format
Use Cases:
  • String formatting in C++ applications
  • Logging and debugging output
  • Data serialization and reporting
  • Template-based text generation
Alternatives:
  • iostreams – More verbose and less performant than fmt
  • boost::format – Heavier dependency with slower runtime performance
