The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Is bloat in std::unexpected expected?
There are several implementations of compact optionals, see https://github.com/Sedeniono/tiny-optional, and related work & reddit thread.

tiny::optional – a C++ optional that does not waste memory
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).

tiny::optional – a C++ optional that does not waste memory
I tried Implementierung this bundling in a library: https://github.com/foonathan/tiny/blob/master/include/foonathan/tiny/padding_traits.hpp You specialize traits that expose the unused bits in your type, then use them as the base storage for various containers.
What are some alternatives?
When comparing tiny-optional and tiny you can also consider the following projects:
dynamap - Thread-safe and dynamically resized hash map for C++ (header-only)
compact_optional - A template for creating optional-like object with no space overhead
cmake-init - The missing CMake project initializer
libCat - 🐈⬛ A runtime for C++26 w/out libC or POSIX. Smaller binaries, only arena allocators, SIMD, stronger type safety than STL, and value-based errors!
