- Hello.
Welcome to Lesson Five.
This lesson is all about how to organize your data
into interesting data structures.
We'll begin by showing how to create and use arrays.
An array is a fixed size collection
where each element is the same type.
Then we'll see how to create tuples.
A tuple is similar to an array,
except that the elements can be of different types.
Finally, we'll see how to use vectors and maps.
These are standard collection types in the Rust library.
Vector is like a resizable array,
and a map is like a dictionary of key value pairs.
A typical Rust application would make use
of all these data types somewhere or other.
