Ownership & Borrowing. 🦀Rust Smart Contracts

Описание: Welcome back to our NEAR Protocol smart contract series! 🚀

In this episode, we break down one of Rust’s most powerful safety features — ownership and borrowing — and why they’re essential for building bug-free, memory-safe blockchain applications. Whether you’re new to Rust or already coding NEAR smart contracts, mastering these concepts will help you avoid common pitfalls and write cleaner, more reliable code.

📌 What You’ll Learn in This Video:

What is Ownership? How Rust manages memory and prevents crashes by moving or copying values.
Borrowing Explained: The difference between immutable (&) and mutable (&mut) references, and when to use each.
Common Mistakes & How to Avoid Them:
Using moved values accidentally
Creating multiple mutable borrows
Forgetting to dereference in NEAR contracts
Best Practices for NEAR Contracts:
When to use &str vs String
When to clone() and when to borrow
Tips to keep borrow scopes short and avoid conflicts

💡 Why This Matters:
Rust’s ownership system isn’t just theory — it’s your first line of defense against memory leaks, runtime errors, and unpredictable contract behavior. Understanding it is crucial if you want to ship production-ready NEAR dApps.
