Elements of Rust – Core Types and Traits

A quick-reference map of the Rust type system, with links to documentation. This resource is referenced throughout the video course.

1. Why Rust is Safe

Rust is a systems language with just as much control and performance as C or C++. And yet, it guarantees memory safety and thread safety at compile-time. How is that possible?

2. Hello Rust

The basics of Rust syntax: functions, variables, scalar types, ranges, conditionals and loops.

3. Panic! Premium

Learn how to manage unexpected errors in Rust – division-by-zero, integer overflow, out-of-bounds array access, and failed assertions. Rust's default setting for panic handling is probably not the one you want.

4. Structs and Resources

Structs can hold plain data, or they can represent unique resources with protection against copying.

5. Destruction Premium

With no garbage collector, Rust relies on deterministic destructors to manage the lifecycle of objects. Write types that safely encapsulate raw resources, reason confidently about the scopes of locks, and understand the limitations of Rust's guarantees around resource leakage.

6. Enums and Polymorphism

Enums hold named alternatives (variants) with associated data. If you've never worked in a language with strong support for tagged unions, you'll wonder how you ever lived without them.

7. Arrays and Slices

Rust has distinct types for fixed-length arrays, dynamic arrays, and slices. A slice is a borrowed reference into a sequence of elements owned by some other variable.

Compile Time

A mini-lesson in which we disassemble a compiled executable to see what's in there.

8. Generics and Monomorphization

Generics allow code to be reused with many different types. Generic parameters are resolved to concrete types at compile-time.

9. Traits are Interfaces

A trait specifies an interface, a capability that types can choose to implement. Trait bounds specify the capabilities required for a generic type to work with an API.

The Stack

To prepare for a deeper understanding of borrowed references, a mini-lesson about the stack, stack frames, the stack pointer, registers, memory and the instruction set.

10. Three Ways to Fix Any Borrowing Error

With a clear understanding of Rust's borrowing rules, fighting the borrow checker need not be painful.
