Live Stellar Workshop | Week 2, Day 2: Rust Variables & Data Types

Описание: Welcome back to Week 2, Day 2 of the Live Stellar Workshop! Continuing our Rust Crash Course, today we dive into the foundational building blocks of the language: Variables, Mutability, and Data Types.

When engineering secure smart contracts on the Stellar network or developing robust full-stack solutions, understanding exactly how your data is stored and manipulated at a systems level is critical. In this session, we break down Rust's strict type system, explore the difference between scalar and compound types, and look at how Rust's default immutability protects your applications from unexpected bugs.

What We Cover in This Session:
Variables & Mutability: Understanding let vs. let mut and why Rust makes variables immutable by default.

Constants: How const differs from standard variables in global scopes.

Shadowing: A powerful Rust feature for transforming data without creating new variable names.

Scalar Data Types: Deep dive into Integers, Floating-point numbers, Booleans, and Characters.

Compound Data Types: Grouping multiple values together using Tuples and Arrays.

Practical Coding: Writing and running examples in our local Cargo environment.
