Qdf: Go serializer with raw‑byte queries and a smaller footprint than protobuf

Qdf is a Go library that serializes data structures into a compact binary format. It allows callers to query the raw bytes of a serialized object directly. The library is positioned as smaller in size than Google's protobuf format. Qdf targets scenarios where minimal payload and fast parsing are critical. It is open source and hosted on GitHub under the user alex60217101990. The repository includes source code, build instructions, and usage examples. Developers can import Qdf to replace or complement existing serialization solutions. The project aims to provide a simple, efficient alternative for Go applications.
