At a high level, traits are most often used with generics as a powerful way to write reusable code, such as the generic greet function shown here. When you call this function with a concrete type, the Rust compiler effectively generates a copy of the function that works specifically with that type. This process is also called monomorphization.
One of our best successes has been building an agentic team called the Marketing Studio to roll out in product campaigns end to end. It used to take a team of five or six groups coming together over three or four weeks to figure out, who are we targeting? What’s the message? How do we build the creative assets? Where do we place them? How do we optimize the analytics? We now have a team of AI agents that play all of those roles and within two hours can optimize campaigns. We’re seeing better conversion rates as a result.
