Using gst-plugins-rs signalling server inside application

Is there a way to use gst-plugins-rs/net/webrtc/signalling/src/bin/server.rs outside of the webrtcsink builtin property and without copying and pasting the implementation?

I tried to add this code to my rust based gstreamer project but I get errors with:

use gst_plugin_webrtc_signalling::handlers::Handler;
use gst_plugin_webrtc_signalling::server::{Server, ServerError};

And I’m unsure how to bring those into my project (i.e. Cargo.toml)?
