nanobind is a small binding library that exposes C++ types in Python and
vice versa. It is reminiscent of Boost.Python and pybind11 and uses
near-identical syntax. In contrast to these existing tools, nanobind is
more efficient: bindings compile in a shorter amount of time, produce
smaller binaries, and have better runtime performance.
