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 are going to look at different collections in Rust such as tuples, vectors and hash-maps.
