Appendix C: Glossary

Coming soon

This appendix is an outline. The full draft ships in a follow-up PR.

What this appendix will cover

A short glossary of terms as this book uses them. The intent is to make cross-references precise, not to define every word in Scala.

Terms to include (non-exhaustive):

• Design — an immutable description of how types are wired.
• Session — a runtime context built from a Design; owns singletons and lifecycle hooks.
• Binding — one entry in a Design (bindSingleton, bindImpl, etc.).
• LogSupport — the trait mixed in to give a class a logger.
• Rx — Uni's asynchronous / streaming abstraction.
• Surface — compile-time type reflection used by the codec layer.
• Launcher — the annotation-driven CLI argument parser.
• Codec — a bidirectional translator between bytes (JSON / MessagePack) and Scala values.
