GStreamer can't create element

While using the GStreamer rust crate, when trying to create an element with the factory name being set osxaudiosink.

match gst::ElementFactory::make("osxaudiosink", None) {
}

I keep getting this error

BoolError { message: "Failed to create element from factory name", filename: "/Users/apple/.cargo/registry/src/github.com-1ecc6299db9ec823/gstreamer-0.17.4/src/auto/element_factory.rs", function: "gstreamer::auto::element_factory", line: 204 }
