Practical Binary with Scodec

on YouTube ↗52m

" summary

Scodec uses Shapeless to derive binary encoders and decoders from Scala types, generating derived codecs for case classes and sealed traits via HLists, Coproducts, records and unions; codecs are first-class Encoder/Decoder effects that can fail with rich path-aware error messages pointing to the exact field, and allow explicit formats like an unsigned 13‑bit PID or tagged unions; library includes BitVector, composes codecs, auto-derives sealed‑hierarchy codecs, and achieves real workloads (≈20 Mbps on laptops) often matching or beating hand‑coded solutions.
