A Tour of Rust: Building Command Line Utilities

rust

In this course, you'll learn **practical, project-based programming with Rust**, specifically tailored for someone who understands JavaScripts. 

Learning Rust can be daunting for a JavaScript developer because of differences like manual memory management, the compilation toolchain, the syntax, strong types and more.

While Rust has many great learn resources, like the staple _The Rust Programming Language_ book,  they often lacks specifics for developers coming from interpreted languages like JavaScript.

In _Rust for JavaScript Developers_ you will learn: 

* the fundamentals of Rust
* practical Rust project knowledge and 
* what the analogues are coming from JavaScript.

You'll get comfortable with developing in a new, challenging language and its environment. 

We'll use the Rust `std` library to make simple but non-trivial command line applications, and be empowered to read and understand the technical Rust documentation on your own. 

You'll understand the fundamentals of Rust syntax and tools like `Iterators`, pattern matching, `struct`s, `impl`s, and return types, and be able to use those in your programs. 

You will also be able to draw on your understanding of JavaScript to augment and better grok these new Rust concepts and ease Rust's notorious learning curve.

In this course, you'll be learning the fundamentals of practical Rust, from the perspective of a JavaScript developer.

So, to program in Rust first we have to install Rust. To do that, we'll use Rustup, which is sort of like the 

 tool from the Node ecosystem. It lets us manage Rust versions, switch between those versions easily, and install other Rust tools.

To install rustup and then Rust, we can go to

## Install Rust

So, to program in Rust first we have to install Rust. To do that, we'll use Rustup, which is sort of like the `nvm` tool from the Node ecosystem. It lets us manage Rust versions, switch between those versions easily, and install other Rust tools.

To install rustup and then Rust, we can go to [rust-lang.org](rust-lang.org), click install, and copy this script into a terminal. Select 1) for the default installation settings. After it finishes, you might have to restart your terminal or run this `source` command.

Let's check that it worked with a `rustup --version`. Also check `cargo --version` -- cargo is the equivalent to `npm`. Then finally let's also check `rustc --version`. `rustc` is the barebones Rust compiler which we'll see in action in just a moment.

Alright, so in order to program the Rust first we have to install Rust.

And to do that we'll use RustUp which is sort of like NVM from the node

It lets us manage Rust versions and install some other Rust tools and is

Clicking install up here and using this command.

It'll ask for some installation config and we can just pass the default.

And once you do this you might need to either source that file or restart your

So now let's check make sure that it worked by running RustUp version and we

We'll also check cargo version and cargo is the Rust ecosystem equivalent of N

Finally we'll just take a look at rustseed.version

and rustsea is the standard bare bones rust compiler which we'll see an action
