<html> <p>In this tutorial video, we look to filling a few of the gaps in our knowledge. We look at the last major collection types in Rust, the <strong>Vector</strong> and the <strong>Hashmap</strong>. Both the Vector and the Hashmap are very important collection types in Rust. We also look at how we can coerce a primitive from one type to another using <strong>Casting</strong>. This is a very useful construct because it lets us deal with some problems without having to re-create new types or new functions. We look at some syntactic sugar statements in the <strong>If-Let</strong> and <strong>While-Let</strong> match/binding statements and we talk about how they are not as exhaustive as a proper Match statement. They also allow us to write less verbose code as a result. Finally, we take a look at the <strong>Result Enum</strong> and how we can use it for error handling in a different way from the <strong>Option Enum</strong>. </p> <p><iframe width="560" height="315" src="https://www.youtube.com/embed/oEy6bq8MTBc" frameborder="0" gesture="media" allow="encrypted-media" allowfullscreen></iframe></p> <p>Edit: <em>I just realized after re-watching the video that I misspoke a few times in the video (calling While-let if-while etc). I was a exhausted when I made this video and I hope it does not detract from your learning experience. </em></p> <p><br></p> </html>
