## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 4120, "days_push": 765, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
An online book (built with mdbook) that teaches basic and advanced Rust programming by guiding readers through implementing six different linked lists. It covers pointers, ownership, borrowing, generics, pattern matching, testing, and unsafe Rust including raw pointers and aliasing rules.

## Use cases
- learn rust by implementing linked lists
- understand ownership and borrowing in rust
- learn unsafe rust and raw pointers
- understand box rc arc and nonnull pointer types
- rust tutorial for intermediate programmers
- practice writing safe and unsafe data structures in rust

## When to choose
- you want a hands-on, project-based introduction to Rust's memory model
- you struggle with the borrow checker and want deep explanations
- you want to learn unsafe Rust concepts like stacked borrows and variance

## When to avoid
- you need a production linked list library rather than a tutorial
- you want a general Rust beginner book not focused on data structures
- you need a quick reference rather than a long-form tutorial

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, testing, developer-tools
- domain: tutorials, programming-languages, education
- platform: rust, cross-platform
- tags: rust, linked-lists, book, mdbook, ownership, unsafe-rust, pointers, borrow-checker, algorithms
