libCat

🐈‍⬛ A runtime for C++23 w/out libC or POSIX. Smaller binaries, only arena allocators, SIMD, stronger type safety than STL, and value-based errors! (by Cons-Cat)

tiny-optional

Replacement for std::optional that does not unnecessarily waste memory (by Sedeniono)

  • tiny::optional – a C++ optional that does not waste memory
    6 projects | /r/cpp | 23 Oct 2022
    tiny::optional is a header-only C++ library for x86/x64 intended to be a drop-in replacement for std::optional with the twist that it does not require additional memory for bools, floats, doubles and raw pointers. For example, a std::optional has twice the size of a raw double because of 7 padding bytes after the internal bool. These wasted bytes can have a notable impact on performance in memory bound applications. On the other hand, a tiny::optional has the size of a double by exploiting unused bit patterns (i.e. by exploiting platform specific behavior).
