Optionals type, which handles the absence of a value. Optionals say either "there is a value, and it equals x" or "there isn't a value at all". An Optional is a type on its own, actually one of Swift’s new super-powered enums. It has two possible values, None and Some(T), where ...

In stable Rust you create a Box by using the Box::new function. let boxed_int: Box<i32> = Box::new(1);

Because Boxes implement the Deref<Target=T>, you can use boxed values just like the value they contain. let boxed_vec = Box::new(vec![1, 2, 3]); println!("{}", boxed_vec.get(0)); If you want to pattern match on a boxed value, you may have to dereference the box manually. struct...

If you try and create a recursive enum in Rust without using Box, you will get a compile time error saying that the enum can't be sized. // This gives an error! enum List { Nil, Cons(i32, List) } In order for the enum to have a defined size, the recursively contained value must be in...

As a way of subdividing Ada programs, packages may have so-called children. These can be packages, too. A child package has a special privilege: it can see the declarations in the parent package's private part. One typical use of this special visibility is when forming a hierarchy of derived types ...
