  • Data Types
  • How Functions Work
  • Comments
  • Control Flow

• Understanding Ownership

  • What is Ownership?
  • References & Borrowing
  • Slices

• Using Structs to Structure Related Data

  • Defining and Instantiating Structs
  • An Example Program Using Structs
  • Method Syntax

• Enums and Pattern Matching

  • Defining an Enum
  • The match Control Flow Operator
  • Concise Control Flow with if let

Basic Rust Literacy

• Modules

  • mod and the Filesystem
  • Controlling Visibility with pub
  • Referring to Names in Different Modules

• Common Collections

  • Vectors
  • Strings
  • Hash Maps

• Error Handling

  • Unrecoverable Errors with panic!
  • Recoverable Errors with Result
  • To panic! or Not to panic!

• Generic Types, Traits, and Lifetimes

  • Generic Data Types
  • Traits: Defining Shared Behavior
  • Validating References with Lifetimes

• Testing

  • Writing tests
  • Running tests
  • Test Organization

• An I/O Project: Building a Command Line Program

  • Accepting Command Line Arguments
  • Reading a File
  • Refactoring to Improve Modularity and Error Handling
  • Developing the Library’s Functionality with Test Driven Development
  • Working with Environment Variables
  • Writing Error Messages to Standard Error Instead of Standard Output

Thinking in Rust

• Functional Language Features: Iterators and Closures

  • Closures: Anonymous Functions that Can Capture Their Environment
  • Processing a Series of Items with Iterators
  • Improving Our I/O Project
  • Comparing Performance: Loops vs. Iterators

• More about Cargo and Crates.io

  • Customizing Builds with Release Profiles
  • Publishing a Crate to Crates.io
  • Cargo Workspaces
  • Installing Binaries from Crates.io with cargo install
  • Extending Cargo with Custom Commands

• Smart Pointers

  • Box<T> Points to Data on the Heap and Has a Known Size
  • The Deref Trait Allows Access to the Data Through a Reference
  • The Drop Trait Runs Code on Cleanup
  • Rc<T>, the Reference Counted Smart Pointer
  • RefCell<T> and the Interior Mutability Pattern
  • Creating Reference Cycles and Leaking Memory is Safe

• Fearless Concurrency

  • Threads
  • Message Passing
  • Shared State
  • Extensible Concurrency: Sync and Send

• Object Oriented Programming Features of Rust

  • Characteristics of Object-Oriented Languages
  • Using Trait Objects that Allow for Values of Different Types
  • Implementing an Object-Oriented Design Pattern
