Question 1

What is Rust programming language?

Accepted Answer

Rust is a systems programming language designed for performance, safety, and concurrency. It is statically typed and provides features like memory safety, zero-cost abstractions, pattern matching, and more. Rust is primarily focused on empowering developers to build reliable and high-performance systems while minimizing the risk of errors such as null pointer dereference or data races.

Question 2

How does Rust ensure memory safety?

Accepted Answer

Rust enforces memory safety through its ownership system and borrowing rules, without the need for a garbage collector. This system allows Rust to manage memory at compile-time, ensuring that there are no dangling references, double frees, data races, or memory leaks.

Question 3

What is the difference between Rust and other systems programming languages like C or C++?

Accepted Answer

While Rust draws inspiration from languages like C and C++, Rust emphasizes memory safety, concurrency, and modern language features. The most significant difference is the ownership system in Rust, which prevents common programming errors while providing similar low-level control and performance as C and C++.

Question 4

Can I use existing C or C++ code with Rust?

Accepted Answer

Yes, Rust has built-in support for interacting with C code using the Foreign Function Interface (FFI). You can easily call C functions from Rust or expose Rust functions to be called from C code. Likewise, you can utilize `bindgen` or `cpp` crates to generate bindings for C++ code.

Question 5

Is Rust suitable for Web development?

Accepted Answer

Although Rust was initially designed for systems programming, its features and the growing ecosystem make it a strong choice for web development. With frameworks like Actix and Rocket, you can build robust and high-performance web applications. Additionally, Rust's compatibility with WebAssembly allows you to use Rust for tasks that run directly in the browser.
