Pull Request Overview
This PR introduces AnnotatedCodec to the typed-protocols library, which enables retaining the original bytes received from the network during message decoding. This is particularly useful for cryptographic applications where the exact received bytes must be preserved for signature verification.
Key changes include:
- Generalization of the
Codectype toCodecFwith type aliases for backward compatibility - Creation of a new
codec-propertieslibrary for testing utilities - Addition of comprehensive QuickCheck properties for the new annotated codec functionality
