Herding types with Scala macros
summary
Shows a small Scala library that uses compile-time reflection and Scala macros to generate per-type serializers and deserializers for a schemaless key‑value store (Aerospike style), eliminating the dozens of boilerplate reader/writer methods for keys and bins. Macros materialize macro materialized writers and readers at compile time, emit code that handles strings, numbers, maps and collections, allow explicit serializer selection, come with tests for many type mappings, and are used successfully in production.
