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

NEAR RPC docs got a refresh 🔄

The Access Keys page is now easier to scan and copy into your code: a quick table of the four methods up top, clear params, and ready-to-use examples in JSON / JavaScript / HTTPie. There’s also a one-click “Try it out on Lantstool” to run calls immediately, plus a short Best Practices section 🗯

Rust Smart Contracts on NEAR — Lesson 10 🦀

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)

Rust Smart Contracts on NEAR — The Last Lesson 🦀

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)

New RFP from the NEAR Infrastructure Committee ✨

TEE-secured Price Oracle
⏳ Deadline: 24 days left

The goal: build and maintain a Price Oracle on NEAR powered by TEEs rather than crypto-economic security.

Beyond serving as critical infra for the ecosystem, this oracle will also be a real-world product leveraging the Shade Agent Framework 👍
