These bindings depend on the Nix C API, which is currently only available in nix
master. It's a moving target, and while we try to catch up, sometimes the API is
broken so you must pull nix from the same revision that's tracked in this
flake's nix, and make both nix.dev and pkg-config available in your
buildInputs for the CGO bindings to work. Consult the flake.nix for an
example.
See godoc for API and examples.
