I'll add a (lone?) voice for diving in to the deep end straight away:
https://doc.rust-lang.org/reference/
https://doc.rust-lang.org/nomicon/
Documentation aimed at beginners often assumes a lack of prior programming experience, which is useful if you are (for example) a high-school student learning about pointers and abstraction but IMO not a good use of time for most people posting on Hacker News.
The Rust reference manual is well-written and comprehensive for basic Rust, and the Rustonomicon has often answered my questions about more advanced topics (FFI, concurrency).
