In Rust, we may refer to any list as a sequence of items. A list can be fixed size like an array or resizeable collection types – Vec, VecDeque, and LinkedList. Meaning the list can grow or shrink at runtime.
Rust – Display Contents of Array, Tuple, HashMap and Vector
When using collection types, we sometimes do not want to use loops to display each value. For example, in Rust, we can display the content of an Array, Tuple, HashMap (Map), or Vector without loops using the Debug trait. Rust

Swapping between Vec elements in Rust can be a little tricky. The get method returns Option<&T>, and the lone swap method accepts an index and a value – not a reference. There is an alternative, though. But it uses unsafe codes.
