MCQs on Introduction to Rust | Rust
Rust is a systems programming language known for its focus on safety, performance, and concurrency. It’s designed to prevent memory errors and data races while providing low-level control. This set of 30 multiple-choice questions covers Rust’s basic concepts, installation, environment setup, writing the first program, and using the Rust compiler.
