Advanced Rust Concepts
Test your knowledge of lifetimes,concurrency,and async programming in Rust.
1. What is the primary goal of Rust's ownership system?
Memory safety without a garbage collector
Faster execution than C++
Simplified syntax for beginners
Automatic parallelization of code
2. Which of the following are valid trait bounds in Rust?
T: Clone + Debug
T: Send + Sync
T: 5
T: !Copy
3. Lifetimes in Rust affect the runtime behavior of a program.
True
False
4. What macro is used to handle recoverable errors by propagating them upward (abbrev.)?
5. Which keyword is used to define an asynchronous function in Rust?
async
await
future
nonblocking
6. Rust's `Box<T>` is a smart pointer that stores data on the heap.
True
False
7. Which of the following are valid uses of `unsafe` blocks in Rust?
Dereferencing a raw pointer
Calling an `unsafe` function
Accessing a mutable static variable
Using generics
8. What is the name of the trait that allows a type to be converted into an iterator?
9. What is the purpose of the `Sync` trait in Rust?
Allows a type to be sent across threads
Allows shared references to be sent across threads
Enables mutable access to data
Marks a type as immutable
10. Rust macros are expanded at compile time.
True
False
11. Which of the following are examples of smart pointers in Rust?
Box<T>
Rc<T>
Arc<T>
&str
12. What keyword is used to define a custom derive macro in Rust?
13. What is a limitation of trait objects in Rust?
They require the trait to be 'Sized'
They use static dispatch
They cannot wrap generics
They have dynamic dispatch overhead
14. The `?` operator can only be used in functions that return `Result<T, E>`.
True
False
15. Which of the following are features of Rust's error handling model?
Explicit recoverable errors with `Result<T, E>`
Unrecoverable errors with `panic!`
Checked exceptions at runtime
The `Error` trait for custom error types
