itlib
A collection of single-header C++ libraries that extend or provide alternatives to the C++ standard library.
What is itlib?
itlib is a collection of single-header C++ libraries that extend or provide alternatives to the C++ standard library. It offers backports of modern C++ features (like std::span and std::expected) for older standards, along with performance-optimized containers and utility extensions. The project solves the need for lightweight, modular libraries that fill gaps in the standard library without heavy dependencies.
C++ developers working with C++11 or later who need modern standard library features, performance-optimized containers, or lightweight utility libraries in a single-header format.
Developers choose itlib for its ease of integration (each library is standalone), compatibility with multiple C++ standards, and performance-focused alternatives to standard containers like flat_map and small_vector. It’s a practical alternative to larger libraries like Boost for specific use cases.
