The Box<T>
type in Rust is a smart pointer that allows heap allocation for values, enabling efficient management of large data or data with unknown sizes at compile time.
In this challenge, you'll work with a custom struct Animal
and use Box<T>
to manage its memory. You will also implement two functions to access the struct's fields by dereferencing the boxed instance.
Implement the create_animal
function to return a Box<Animal>
containing a new Animal
instance.
Define another function, access_animal
, that takes a Box<Animal>
and returns a tuple (String, u8)
representing the animal's name and age. Use dereferencing to access the fields.
Box::new(struct_instance)
.*
operator to dereference the box and access its value.
