Certainly! Here are a few code samples in Rust that demonstrate some of its memory-safe features:

1. Ownership and Borrowing:
```rust
fn main() {
    let mut data = vec![1, 2, 3];
    modify_vector(&mut data);
    println!("Modified vector: {:?}", data);
}

fn modify_vector(vec: &mut Vec<i32>) {
    vec.push(4);
}
```
In this example, we pass a mutable reference (`&mut`) of the `data` vector to the `modify_vector` function. This demonstrates Rust's ownership and borrowing system, where ownership of `data` is temporarily borrowed by the function. This ensures that there are no data races or multiple mutable references, promoting memory safety.

2. Option and Result Types:
```rust
fn divide(a: i32, b: i32) -> Option<f64> {
    if b != 0 {
        Some(a as f64 / b as f64)
    } else {
        None
    }
}

fn main() {
    let result = divide(10, 2);
    match result {
        Some(value) => println!("Result: {}", value),
        None => println!("Cannot divide by zero"),
    }
}
```
In this code, the `divide` function returns an `Option<f64>` type to handle the possibility of division by zero. This allows for explicit handling of potential errors, preventing unexpected crashes or undefined behavior.

3. Struct and Lifetimes:
```rust
struct Person<'a> {
    name: &'a str,
    age: u32,
}

impl<'a> Person<'a> {
    fn new(name: &'a str, age: u32) -> Person<'a> {
        Person { name, age }
    }

    fn introduce(&self) {
        println!("Hello, my name is {} and I am {} years old.", self.name, self.age);
    }
}

fn main() {
    let person = Person::new("Alice", 25);
    person.introduce();
}
```
In this example, we define a `Person` struct with a lifetime specifier (`'a`) to indicate that the `name` field is borrowed from an external source. The lifetime specifier ensures that the borrowed reference is valid for the lifetime of the struct. This promotes memory safety by preventing the usage of dangling references.

These code samples highlight some of the memory-safe features of Rust, such as ownership and borrowing, option and result types for error handling, and lifetimes for managing references. Rust's emphasis on safety without sacrificing performance makes it a powerful language for systems programming.
