Rust #1.2 - Implementing State Management: Blockchain Module Using BTreeMap

In this lesson, we dive into adding state to our Rust blockchain module by implementing a way to store user balances. We'll use Rust's standard library, specifically the BTreeMap collection, to create a key-value store for balances. You'll learn how to define fields in your Pallet struct, specifying types and ensuring efficient memory use. We also cover creating methods for the struct, starting with the new method to instantiate the Pallet. By the end of this video, you'll have a foundational understanding of managing state in your Rust blockchain applications, setting the stage for more advanced functionality like balance transfers.
