rustvla | Rust practice challenges

Beta

Generics in Rust allow you to write code that works with different types without duplicating code for each specific type. They are commonly used in functions, structs, enums, and methods to make your code more reusable and flexible.

For this challenge, you will implement a generic struct ItemContainer that can store any type of item and provide methods to retrieve and manipulate the item.

Your Task

Define a generic struct ItemContainer<T> with a single field item: T.
Implement a method get_item that returns a reference to the item.

Hints

If you're stuck, here are some hints to help you solve the challenge:

Define the struct as ItemContainer<T>. e.g.

struct ItemContainer<T> {
  item: T,
}
