sample code for configuring bridges in rust code

I'm building a rust program which is supposed to route network connections over tor + plugable transports. (https://gitlab.com/guardianproject/arti-mobile-ex/-/issues/1)

So I would like to request some sample code for configuring arti to establish connections over a bridge. More specifically, about how to make use of BridgeConfigBuilder. (Or if that's the wrong struct, a similar configuration)

(@ahf hinted I should open this issue, on tor dev chat, since this might be interesting for other implementers too.)
