Rust Book

This is a personally annotated copy of the "The Rust Programming Language"¹.

Why Rust

For me, I've never really been exposed to low-level systems programming, having majored in Informatics at UC Irvine precisely to avoid it (and well, math). My first language was Visual Basic 6, and even though I've grown to love strong, static langauges, I've never really used C, or anything like it, for anything substantial.

I'd love to Rust to learn more about:

• Lower-level system details, such as memory usage
• Using non-traditional languages
• Mastering the borrow checker

Rust, is well, also pretty cool:

Unless otherwise specified, the only tools required to be installed are:

• An IDE (VSCode with rust-analyzer preferred, but any will do).
• Rustup and Cargo, often through the official website.
• A linker, such as xcode-select, Clang, or MSVC.

When possible, copies of other source material, such as PDFs or images, should be cached in this repository so that the only thing required to interact with this repository is an installation of Rust, an IDE, a linker, and a clone.

To verify, run ./CHECK.sh.

Creating a new chapter

cargo new chapter/00-chapter-name --name chapter-name --vcs none

Then, edit Cargo.toml and add the new workspace member:

members = [
  # ...
  "chapter/00-chapter-name",
]

Adding dependencies

cargo add package-name -p chapter-name
