Too much flexibility can break your Rust code — and the Abstract Factory pattern can save you.
In this video, we’ll start with a small Rust application that works fine… until a new requirement forces us to make it “flexible.” That flexibility quickly turns into a misconfiguration nightmare.
I’ll show you:
How we accidentally created a problematic generic design
Why Rust’s type system can’t save us in this case
How the Abstract Factory pattern works
Multiple Rust implementations: generics, associated types, trait objects, and enums
How they compare in readability and performance
If you already know the Abstract Factory, stick around for the deep dive into Rust-specific implementations — we’ll explore the trade-offs and see which one might fit your next project best.
