This repository is a cheat sheet for the Rust programming language, offering a quick reference for syntax, common commands, and language features. It is primarily aimed at developers who are learning or need a refresher on Rust, providing concise examples for various programming constructs.

How It Works

The cheat sheet covers fundamental Rust concepts, including syntax, package management with Cargo, mutability, data types (primitives, arrays, vectors, tuples, strings), control flow (if, match, loops), error handling (Option, Result, panic), functions, closures, structs, enums, collections (HashMap, HashSet), macros, and basic file I/O. It also touches on more advanced topics like iterators, traits, concurrency (Rayon), FFI, and memory management concepts like ownership and borrowing.

Quick Start & Requirements

• Install Rust: Follow instructions at https://www.rust-lang.org.
• Basic Usage: Compile and run Rust code using rustc and ./<executable>, or manage projects with cargo run.
• Dependencies: Primarily requires a Rust toolchain. Some advanced examples might suggest external crates (e.g., rand, regex, itertools, clap, cc).

Highlighted Details

• AI Integration: The README notes that AI tools like ChatGPT can often provide faster answers for specific Rust tasks than traditional cheat sheets.
• Comprehensive Coverage: Includes syntax, standard library features, common patterns, and even advanced topics like FFI and concurrency.
• Practical Examples: Demonstrates concepts with short, runnable code snippets.
• Error Handling Focus: Emphasizes Rust's Option and Result types for robust error management.

Maintenance & Community

The repository is a personal project by "donbright." There's no explicit mention of active maintenance, community channels, or a roadmap.

Licensing & Compatibility

The README does not specify a license.

Limitations & Caveats

The README explicitly states that the cheat sheet contains errors, typos, and pedagogical omissions, and some content may be outdated due to Rust's ongoing development (2019-2022). It also highlights the increasing obsolescence of such sheets due to AI assistance.
