What is Box?
A Box in Rust is a smart pointer that allocates memory on the heap. It's primarily used to store data that has a size that's not known at compile time, or when you want to transfer ownership of data without copying it. Think of it as a way to put data on the heap and access it through a pointer, ensuring that the data is automatically deallocated when the Box goes out of scope.
