Rust Smart Contracts on NEAR — Lesson 6 🦀

Conditions (if, else, else if) and Compound Conditions (&&, ||)

When you’re building NEAR smart contracts in Rust, conditional logic is how your code makes smart choices. In this lesson, you’ll learn how to express rules, handle branches safely, and keep your dApps predictable and clear 💥

✏️ What you’ll learn:
🔴 What if / else are — making decisions from contract state & input
🔴 Comparison operators — ==, !=, <, <=, >, >= in practice
🔴 Else if chains — checking multiple cases in sequence
🔴 Compound conditions — combining rules with && (AND) and || (OR)
🔴 Live example — compile, deploy, and test outcomes based on conditions

🚨 New NDNA (#5) is live

AI tools like Strawberry Computer promise to make coding as simple as describing your idea — “vibe coding” that can spin up apps in minutes. But if shipping becomes effortless, what happens to security, taste, and trust? 🤔

This week we look at the growing divide:
🔷 AI can generate code, but it can’t generate judgment
🔷 The flood of cookie-cutter, insecure apps — and what’s at stake when security fundamentals are skipped
🔷 Why the future belongs to builders who blend speed with product sense and rigorous testing

From insecure clones to the next wave of Web4 apps, the question isn’t whether AI can build — it’s whether the products are worth using 🗯

NDNA is an opinionated weekly newsletter and podcast looking at the news in and around the NEAR developer ecosystem.

Rust Smart Contracts on NEAR — Lesson 7 🦀

Loops (for, while) & Safe Iteration

When you’re building NEAR smart contracts in Rust, loops power batch actions and list processing. In this lesson, you’ll learn to iterate efficiently, avoid unbounded work, and keep gas predictable 💥

✏️ What you’ll learn:
🔴 What loops are — repeating logic without duplicating code
🔴 For loops — ranges & iterators over collections you control
🔴 While loops — explicit exit conditions and state-driven flows
🔴 Step control — .step_by(), break, continue, enumerate()
🔴 Gas-safety patterns — caps, pagination/chunking, and early exits

Rust Smart Contracts on NEAR — Lesson 8 🦀

Match & Enums

Enums + match = expressive, total, bug-resistant logic. In this lesson, you’ll model contract state clearly, replace magic numbers/strings, and make branching explicit — all with compile-time guarantees 💥

✏️ What you’ll learn:
🔴 What enums are — and when to use them instead of ints/strings
🔴 match fundamentals — exhaustive branches, _ wildcard, guards
🔴 Domain modeling — UserTier::{Basic, Premium, VIP} and real logic
🔴 Storage & ABI tips — deriving traits, Borsh for state, Serde for views
🔴 Safety patterns — avoiding partial matches and hidden panics

Rust Smart Contracts on NEAR — Lesson 9 🦀

Arrays
What should we cover next? Drop it in the comments ✍️

Arrays look simple — fixed-size, same-type values — but in smart contracts they shine: predictable memory, fast lookups, and clear, bug-resistant logic. In this lesson we’ll use arrays to model real gameplay and governance data, and show when to reach for Vec or NEAR SDK collections instead 💥

✏️ What you’ll learn:
🔴 Array basics — declaring [T; N], indexing, iteration
🔴 Modern ops — iter().max(), contains(), swap(), sort()
🔴 Mutation patterns — updating scores, tallies, and snapshots safely
🔴 Safety tips — bounds checks with get(), avoiding panics, chunking work for gas
🔴 Choosing the right tool — arrays vs Vec vs NEAR SDK Vector for persistent state

HashMap
What should we cover next? Drop it in the comments ✍️

Need fast key → value lookups? Use HashMap. In this lesson we model DeFi/NFT data, show safe updates, and when to switch to NEAR SDK’s persistent maps 💥

✏️ What you’ll learn:
🔴 Basics — HashMap<K, V>, new(), insert(), get(), contains_key()
🔴 Entry API — entry().or_insert() for clean increments/updates
🔴 Mutation + Option — remove(), retain(), unwrap_or, if let, ?
🔴 Safety — chunk work for gas, avoid unbounded loops; HashMap (in-call) vs UnorderedMap/LookupMap (persisted)

Vectors

Need ordered, growable lists? Use Vec<T>. In this lesson we model real dApp data, walk through clean update patterns, and note when to switch to NEAR SDK’s persistent collections 💥

✏️ What you’ll learn:
🔴 Basics — Vec<T>, Vec::new(), vec![], push(), indexing, .len()
🔴 Advanced ops — pop(), remove(i), insert(i, v), retain(), position(), sum()
🔴 Safety & perf — preallocate with with_capacity(), avoid unbounded loops, chunk work for gas; Vec (in-call) vs near_sdk::collections::Vector (persisted)
