fixed-containers
A header-only C++20 library providing fixed-capacity, constexpr containers with identical APIs to their std equivalents.
What is fixed-containers?
C++ Fixed Containers is a header-only C++20 library that provides fixed-capacity versions of standard library containers like vectors, maps, and strings. It solves the problem of dynamic memory allocation by declaring container capacities at compile-time, enabling deterministic memory usage, constexpr evaluation, and direct serialization. The library is designed for scenarios where heap allocations are undesirable or impossible, such as embedded systems, real-time applications, and compile-time computation.
C++ developers working on performance-critical, embedded, or real-time systems where dynamic memory allocation is prohibited or needs to be minimized. It is also valuable for developers leveraging modern C++20 features for compile-time programming and template metaprogramming.
Developers choose C++ Fixed Containers for its zero-overhead, header-only design that provides drop-in replacements for standard containers with fixed capacities. Its unique selling points include full constexpr support, identical APIs to std containers for easy adoption, and rich enum features that enhance type safety and eliminate common enum-related errors.
