Use the Rust Vec Type for Dynamically Expanding Arrays 🦀

In this video, we'll explore the Rust Vec type in the std::vec module. Vec is useful as a dynamically-sized array, and provides many helper methods for adding items, removing items, joining multiple Vec objects together, reserve additional system memory, and more!

There's a vec! macro in Rust that simplifies instantiating a Vec. You can use the .push() method to add items to a mutable Vec. The .append() method on Vec allows you to join another Vec, with the same underlying data type, to itself. The .remove() method will delete an item from a Vec at a specific index. The .reserve() method can be used to reserve extra system memory if a Vec's size will be increased. You can also use .len() and .capacity() methods to monitor the number of items, and reserved size, for a given Vec.
