1. What is Rust?
- Systems programming language focused on safety and performance
- A web framework
- A database system
- A JavaScript library
Show answer
Answer: Systems programming language focused on safety and performance. Rust is a systems programming language focused on safety, speed, and concurrency. Prevents memory errors at compile time. No garbage collector. Created by Mozilla.
2. What are Rust's main guarantees?
- Fast execution
- Easy syntax
- Automatic optimization
- Memory safety, thread safety, no data races
Show answer
Answer: Memory safety, thread safety, no data races. Rust guarantees memory safety without garbage collection, prevents data races at compile time, and ensures thread safety through its ownership system. Zero-cost abstractions.
3. How do you declare a variable?
- var x = 5;
- int x = 5;
- let x = 5;
- x := 5
Show answer
Answer: let x = 5;. Declare variables with let: let x = 5;. Variables are immutable by default. Use let mut x = 5; for mutable variables. Type inference or explicit: let x: i32 = 5;
