Rust Mastery Roadmap

This detailed roadmap will take you from beginner to expert in Rust, covering syntax, memory safety, concurrency, performance optimization, and real-world projects.

---

Phase 1: Rust Fundamentals

✅ Introduction to Rust

• What is Rust? Why is it popular?

• Installing Rust (rustup, cargo)

• Your first Rust program: "Hello, World!"

✅ Basic Rust Syntax

• Variables & Mutability (let, mut)

• Data Types (i32, f64, bool, char, String)

• Control Flow (if, match, loop, while, for)

📌 Mini Projects:

• Basic Calculator

• FizzBuzz Implementation

---

Phase 2: Ownership, Borrowing & Lifetimes

✅ Understanding Ownership

• What is ownership & why is it important?

• Move semantics & shallow vs. deep copies

✅ Borrowing & References

• Mutable & immutable references (&T, &mut T)

• Lifetimes ('a) and why they matter

📌 Mini Projects:

• Memory-safe Text Editor Buffer

• Ownership-based File Reader

---

Phase 3: Structs, Enums & Pattern Matching

✅ Working with Structs & Methods

• Defining structs (struct Person { name: String, age: u8 })

• Implementing methods (impl Person { fn new() -> Self { ... } })

✅ Enums & Pattern Matching

• Defining & using enums (enum Color { Red, Green, Blue })

• Using match for control flow

📌 Mini Projects:

• Simple CLI Address Book

• Basic Banking System (with Structs & Enums)

---

Phase 4: Collections, Iterators & Error Handling

✅ Using Rust’s Collections

• Vectors (Vec<T>)

• HashMaps (HashMap<K, V>)

✅ Iterators & Functional Programming in Rust

• map(), filter(), collect()

• Creating custom iterators (impl Iterator)

✅ Error Handling in Rust

• Result<T, E> & Option<T>

• ? operator & custom error types

📌 Mini Projects:

• To-Do List CLI App

• Word Counter in a File

---

Phase 5: Concurrency & Async Programming

✅ Working with Threads

• Creating & joining threads (std::thread)

• Sharing data safely with Arc<Mutex<T>>

✅ Async Programming with Rust

• async & await syntax

• Using tokio & async-std

📌 Mini Projects:

• Parallel File Downloader

• Async Web Crawler

---

Phase 6: Systems Programming & Performance Optimization

✅ Low-Level Systems Programming

• Unsafe Rust (unsafe, raw pointers)

• Working with C FFI (extern "C")

✅ Optimizing Rust Code

• Benchmarking with cargo bench

• Memory optimizations & zero-cost abstractions

📌 Mini Projects:

• Custom Memory Allocator

• Rust-based CLI Process Manager

---

Phase 7: Web Development & Networking

✅ Building Web Applications in Rust

• Using actix-web & warp

• Creating REST APIs with Rust

✅ Networking & WebSockets

• TCP & UDP with tokio

• Building WebSocket servers

📌 Mini Projects:

• Simple Rust API (CRUD App)

• Real-time Chat App (WebSockets + Actix-web)

---

Phase 8: Rust for Embedded & Blockchain Development

✅ Embedded Systems with Rust

• Using Rust for microcontrollers (no_std, embedded-hal)

✅ Blockchain Development with Rust

• Understanding substrate framework

📌 Mini Projects:

• IoT Sensor with Rust

• Smart Contract on Polkadot (Substrate)

---
