Certainly! I'll provide you with some code examples that illustrate common mistakes related to ownership and borrowing in Rust. For each example, you can determine whether it would compile or not, and I'll explain why it should or should not compile based on Rust's rules.

Example 1: Multiple Ownership Attempt

fn main() {
    let s1 = String::from("hello");
    let s2 = s1;
    let s3 = s1;

Sure, I'd be happy to help you practice recognizing ownership and borrowing violations in Rust! Here are some code examples for you to evaluate:

Example 1:

let mut s = String::from("hello");

let r1 = &s;
let r2 = &s;
println!("{}, {}", r1, r2);

Here are some Rust code examples that involve ownership and borrowing. For each example, determine whether it will compile and explain why or why not based on Rust's ownership and borrowing rules.

Example 1

fn main() {
    let s1 = String::from("hello");
    let s2 = &s1;
    drop(s1);
    println!("s2 says: {}", s2);
}

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional, and may contain IDs of the task / user story we are changing the code for (e.g. SELL-123)
