Build a Blockchain from Scratch with Rust - Rust #3.1 - Generics and Configurable Types

In this lesson, we enhance the readability and flexibility of our Rust blockchain code by abstracting hardcoded types into custom, expressive types. Instead of using hard coded types like string and u32 throughout our code, we create specific types like AccountID, Balance, and BlockNumber. This approach makes our code more understandable and easier to maintain. You'll learn how to define these custom types and integrate them into both the system and balances pallets. By the end of this video, your code will be cleaner, more expressive, and prepared for future modifications without confusion. This video is part of a learning journey created by WEB3DEV.
