ProAbout 12 minutes

By the end you can

Apply ownership and lifetime rules from the Core Guidelines to pool code
Select creational, structural and behavioral patterns only where they reduce variation
Refactor queue and harness code toward clear interfaces without added cost

Builds on The ABI: Name Mangling, Layout and Library Boundaries.
