dpm::static_vector

An implementation of P0843 using C++20. Example usage:

#include <dpm/static_vector.h>

int main()
{
    dpm::static_vector<int, 5> vec{ 1, 2 };
    vec.push_back(3);
    vec.pop();
    return vec.size() - 2;
}

To Build / Install

cmake -B build .
cmake --build build
# Or to build & install
sudo cmake --build build -t install

The CMake target is dpm::static_vector and the find_package is dpm-static_vector.

Note: The constexpr-ness is basically a lie due to the use of reinterpret_cast and the fact that the unitialized_ algorithms aren't constexpr (P2283 proposes making them so).
It should be possible for it to be constexpr for trivial types by using std::array if the types are trivial and by not using the algorithms.
