I have been recently working on Rust with Mongodb to serialize/deserialize structures with a Mongodb collection. I found an article on the internet describing exactly what I am looking for. Unfortunately when I put together some code to test the feature the client.collection_with_type is missing on my system. Perhaps the described functionality no longer exists or has morphed into something else.

I have made sure all my dependencies are using the latest versions of mongo and bson. If there is something I haven't included in my system I would appreciate some direction in finding what I need to add.

The equivalent of .collection_with_type() in the latest 3.x versions is just .collection().

The original .collection() in 1.2.0 as used in your article would always create a Collection<Document> and you'd have to use .collection_with_type() to get a different object type. That was changed in 2.x - there is no longer a default collection type so .collection() works for all collections.
