## Description

_nanobind_ is a small binding library that exposes C++ types in Python and
vice versa. It is reminiscent of
[Boost.Python](https://www.boost.org/doc/libs/1_64_0/libs/python/doc/html)
and [pybind11](http://github.com/pybind/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.

More concretely,
[benchmarks](https://nanobind.readthedocs.io/en/latest/benchmark.html) show up
to **~4× faster** compile time, **~5× smaller** binaries, and **~10× lower**
runtime overheads compared to pybind11. nanobind also outperforms Cython in
important metrics (**3-12×** binary size reduction, **1.6-4×** compilation time
reduction, similar runtime performance).
