I was reading chapter 15 of the book talking about smart pointers, and one of them is called Box<T>
, which is a container and can store at most 1 element in heap.
To be honest, I could not figure out what does it do at first glance, by contrast, some types like HashSet
, BTreeSet
and LinkedList
could be easily understood since they are common technical terms in CS. And because these types are all inside std::collections
module, even though some people may not be familiar with these terms, they can still figure out that they are some kinds of containers which can store multiple elements.
So why Box
is named Box
?
Is it also a technical term in CS or it is only introduced in Rust?
