Rust Learns from Python's Dynamic Capabilities: Reflection with Serde

This article details how the author used Rust and the Serde library to mimic Python's dynamic attribute access (__getattr__) mechanism, creating a clean and user-friendly API for accessing system information. The article thoroughly explains the implementation process, including custom trait, Deserializer, and Visitor implementations, and how to leverage Serde's derive(Deserialize) feature to simplify the code. Ultimately, the author successfully built an efficient and user-friendly Rust library that achieves a Python-like concise API, and discusses alternative approaches and trade-offs.
