Build a Blockchain from Scratch with Rust - Rust #6.3 - Adding Call Macro to Proof of Existence Pallet

In this video, we demonstrate how to streamline the Proof of Existence palette in our Rust blockchain project using macros. By leveraging macros, we automate the generation of enums and dispatch functions, reducing code duplication and aligning with the Polkadot SDK architecture. We'll show you how to isolate functions, apply macro_call, and adjust the main function to integrate the newly generated code efficiently. Watch as we simplify the process of creating and revoking claims, ensuring a more maintainable and scalable codebase. By the end of this tutorial, you'll understand how to use macros to enhance your Rust programming workflow. This video is part of a learning journey created by WEB3DEV.
