Chapter 9 - Optionals - Rust Crash Course 🦀

Part of the Rust Crash Course: Welcome to the Rust Crash Course In this course, we will be learning Rust from scratch. This course is very fast paced and designed for programmers who already have some experience with another programming language such as Dart or JavaScript or Swift. We will talk about variables, constants, ownership, functions, structures, enumerations, collections such as tuples, vectors, hash-maps and iterators, optionals, error handling, lifetime specifiers, traits, pointers, generics, packages, crates, modules and paths, asynchronous programming and we will also create 2 sample applications using Rust to put all these concepts to use! In this chapter we will have a look at what optional values are in Rust and how the Option enumeration represents optionals. We will look at safely unwrapping optional values as well and how we can best use them in a typical Rust application. Timestamps:
