Sequence types in Rust

Sequences are supported in many forms in Rust. The regular array is strictly implemented: it has to be defined at compile time (using literals) and be of a single data type, and cannot change in size. Tuples can have members of different types, but cannot change in size either. Vec<T> is a generic sequence type (of whatever you define as type T) that provides dynamic resizing—but T can only be of a single type. All in all, each of them has its purpose and, in this recipe, we will explore each.
