The Book: start reading now, read it whenever you can, and don't worry if it takes a long time to get through. You will reference it for most of your time using Rust. or try the Rust Book with Quizzes

Affectionately nicknamed “the book,” The Rust Programming Language will give you an overview of the language from first principles. You’ll build a few projects along the way, and by the end, you’ll have a solid grasp of the language.
Rust By Example: like 'The Book', with less docs and more sample code

If reading multiple hundreds of pages about a language isn’t your style, then Rust By Example has you covered. While the book talks about code with a lot of words, RBE shows off a bunch of code, and keeps the talking to a minimum. It also includes exercises!"

(Blog Series) Learn Rust the Dangerous Way (cliffle) "Rust features in context for low-level C programmers"

Existing Rust tutorials are great, but they focus on safe features. This companion tutorial takes an unsafe-first approach that may be more appealing for low-level systems programmers like me.

Rustlings: Rust by Example -style exercises you complete via your own local environment

Alternatively, Rustlings guides you through downloading and setting up the Rust toolchain, and teaches you the basics of reading and writing Rust syntax, on the command line. It's an alternative to Rust by Example that works with your own environment.
Exercism.org: Work through examples in order from "hello world!" to advanced concepts like Doubly-linked lists. Do work in the browser or via your local environment using the exercism CLI, with progress reflected in the web app. Get mentorship and guidance from real people.

We’re building a place where anyone can learn and master programming for free, without ever feeling lost or stupid. We're here to help everyone get really good at programming, regardless of their background. We want to share our love of programming, and help people upskill as part of their upward social mobility.
Comprehensive Rust: From the Google Android team

This is a four day Rust course developed by the Android team. The course covers the full spectrum of Rust, from basic syntax to advanced topics like generics and error handling. It also includes Android-specific content on the last day. The goal of the course is to teach you Rust. We assume you don’t know anything about Rust and hope to: Give you a comprehensive understanding of the Rust syntax and language. Enable you to modify existing programs and write new programs in Rust. Show you common Rust idioms.

Ok, I Think I Know The Basics But How Do I Get Better?!
