- [Instructor] We have been working with enums and numerators that have their variance in Rust, but we haven't dealt directly or intentionally so with option. So in this case, we are going to be exploring a little bit more about what Option is, what can we do about it, and why is such an important part of dealing with not only possible failures or possible problems and errors, but also match and also the very important Some. And Some is also the ability of creating an instance of an Option. And we'll take a look at what that means in a second. Some is also an enum enumerator that has a variant that wraps a value of some type D. (laughs) That sounds pretty dense, but essentially what it means is that you can take any value. So actually let's, if we take a look at Option here and we go to where it's defined, we can take a look at at what it actually means. So it can return either a None or Some value that will have T. T is kind of like the basis of all the types. In this case, it means…
