In the given code, what are the generic parameters X1, Y1, X2, and Y2 used for?

struct Point { x: X1, y: Y1 }

impl Point {   fn mixup(self, other: Point) -> Point { ... } }

What is monomorphization in the context of Rust generics?

How does Rust ensure that using generics does not result in runtime performance costs?

Given the following code, what is the output of the println! macro call?

struct Point { x: X1, y: Y1 }

impl Point {   fn mixup(self, other: Point) -> Point {        Point {            x: self.x,            y: other.y,        }    } }

fn main() {
    let p1 = Point { x: 5, y: 10.4 };
    let p2 = Point { x: "Hello", y: 'c' };

    let p3 = p1.mixup(p2);

    println!("p3.x = {}, p3.y = {}", p3.x, p3.y);
}

Which of the following is a valid reason to use generics in Rust?

What is the conventional name for a generic type parameter in Rust and why is it used?

Given the following function signature fn process(data: &T) -> T, what constraint must be satisfied by type T if the function needs to clone the data?

What is the advantage of using generics over enums when creating data structures that can hold multiple types?

Why might you prefer using a trait bound like T: Display over simply using a generic type T in a function signature?

What is the purpose of specifying trait bounds on generic types?

When defining a method within an impl block for a generic struct, how do you ensure that the method only applies to instances with a specific concrete type?

How does Rust handle generic code differently from languages that use dynamic typing?

Which of the following best describes what generics enable you to do in Rust with respect to code reusability?

Why is the largest function shown below not able to compile?

fn largest(list: &[T]) -> &T {
    let mut largest = &list;
    for &item in list {
        if item > largest {
            largest = item;
        }
    }
    largest
}

Which statement best describes the role of type parameters (e.g., T) in generic function definitions?

Given the following code snippet, what would be a practical reason to implement the PartialOrd trait for a custom struct?

struct Rectangle {    width: i32,    height: i32,}

Which benefit do generics provide in struct definitions compared to using concrete types?

When defining methods on a generic struct, what does it mean when the generic type parameters in the method signature are different from those in the struct definition?

How does monomorphization affect the size of the compiled binary when using generics?

When would using the Option enum with generics be more appropriate than using a specific type?

What could be a possible downside of using too many generic type parameters in a struct or function definition?

Why does calling a method with generic constraints provide compile-time guarantees?

What is one way to improve the readability of code that uses a lot of generic types?

Given the following snippet, which statement would ensure the code will compile successfully?

    return a > b;
}
