Build a Blockchain from Scratch with Rust - Rust #6.2 - Adding Call Macro to Balances

In this lesson, we demonstrate how to use Rust macros to automate the generation of call handling code in our Balances pallet. By leveraging the call macro, we eliminate code duplication and streamline the implementation of calls like transfer in the balances pallet. We walk through the process of splitting the implementation, applying the macro, and adjusting our main program to accommodate these changes. You'll learn how macros can dynamically generate enums, dispatch logic, and more, making your code more maintainable and expressive. Join us to see the power of macros in action and enhance your blockchain development skills. This video is part of a learning journey created by WEB3DEV.
