[Rust Guide] 1.0. Intro

1.0.1 Preface This project (both code and notes) was documented during my self-learning journey with Rust. It might contain inaccuracies or unclear expressions, so I ask for your understanding. If you benefit from it, all the better. 1.0.2 Why Use Rust Rust is reliable and efficient. Rust can replace C and C++ with similar performance but higher safety, and it does not require frequent recompilation to check for errors like C and C++. Key advantages include: Memory safety (prevents null pointer dereferencing, dangling pointers, and data races). Thread safety (ensures multithreaded code is safe before execution). Avoids undefined behavior (e.g., array out-of-bounds, uninitialized variables, or accessing freed memory). Rust provides modern language features (e.g., generics, traits, pattern matching). Rust offers a modern toolchain. Rust's Cargo shares similar principles with Python’s pip. Unlike the cumbersome dependency configuration of C/C++, Cargo provides a user-friendly dependency m
