Learn Openapi, Reflux and Rust

Rust is a modern language that is close to the metal. It's got the performance of C, but with a more friendly syntax and community.

It's also memory safe, and ensures your applications are bug free by catching errors at compile time instead of runtime.

These features make Rust a great choice for developing code for embedded systems, web servers, and CLI apps. You can even compile Rust into WebAssembly in order to run it in-browser!

But as the saying goes, "before you learn to run, you must learn to walk".

In this course, you will write your first Rust application.

Starting from “Hello World” you’ll quickly move on to learning about Rust’s types, configuration files, and the `cargo` package manager along with classics like functions, loops, and handling user input.

More Rust-specific concepts like macros and pattern matching will also be introduced.

Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety.

Write Your First Program with the Rust Language

[Rustlings](https://github.com/rust-lang/rustlings) is a set of exercises that serves as a great introduction to the Rust language. It covers many concepts from the [Rust book](https://doc.rust-lang.org/book/) by asking you to work through sets of exercises.

This collection walks you through Rustlings in a way that explains what's going on in each exercise. We cover everything from basic types to generics and threading.

Learning Rust by Working Through the Rustlings Exercises

This collection contains videos that explore the basic types in Rust, including **Fixed size Integer**, **Pointer sized Integer**, **Boolean**, **Strings**, **Characters**, **Arrays**, **Tuples** and more.

If you're just starting out learning Rust and [wrote your first program](https://egghead.io/courses/write-your-first-program-with-the-rust-language), this collection is the right place to get more familiar with the language!

Basic Types in Rust

Many languages work on a compilation story to WebAssembly, but Rust is already ready for primetime. Why?


- Rust is a stable language and great replacement for C and C++. 
- Due to the reference and borrowing concept, Rust doesn’t need a Garbage Collector and can be used for a production-ready WebAssembly project. 
- The Rust/Wasm team has built some sophisticated tooling for straightforward interoperability between Rust and JavaScript.

This course gives you the tools to compile to WebAssembly with Rust. Over 11 lessons, we’ll set up a project and explore various paths of communication and interoperability between Rust and JavaScript.

Using WebAssembly with Rust

In this course, we will build a ToDo API that stores notes using the OpenAPI Specification (Swagger). We will start with a blank API definition using the Swagger Online Editor. The Swagger definition file will be used to create a Node.js API. Along the way, we will discover how to implement additional details required for a fully functional API requests and responses. We will also learn about the powerful capabilities of Swagger to generate server side code and client libraries.

Open API Initiative (OAI) is focused on creating, evolving and promoting a vendor neutral API Description Format based on the Swagger Specification

In this lesson we’ll create a new Rust project using the `cargo new` command and take a look at some of the generated files.

Create a Rust package with the Cargo package manager

In this lesson we take a look at how `println!()` can be used to output multiple variables using formatter placeholders.

In this lesson you'll learn how to install Rust's toolchain.

In this lesson we’ll create our first “Hello World” Rust program from scratch and will learn how to compile it using `rustc`.

Compile and run a Rust program from scratch

In this lesson we'll learn how to use the `cargo run` command to compile and run a Rust program.

Compile and run a Rust program using Cargo

In this lesson we'll learn how to initialise variables in Rust and how to make them mutable using the `mut` keyword so they can be changed throughout the program.

Variables and Mutability in Rust

In this lesson we'll create a new function that receives parameters and called inside our program's `main()` function.

Write and call a function in Rust

In this lesson we'll briefly discuss the concept of Ownership and Borrowing in Rust, and how expressions can be passed by value and by reference.

Understanding basic Ownership and Borrowing in Rust

In this lesson we'll learn how to read user input from stdin, using Rust's `std::io` module and its `Stdin` object.

In this lesson we'll take a look at the simplest way of handling error in Rust using the `unwrap()` function.

Handle errors with unwrap() in Rust

This lesson discusses how to improve error handling by configuring custom error messages using the `expect()` function.

In this lesson we'll explore how to unwrap a `Result` type using a language feature called Pattern Matching.

Handle errors in Rust using Pattern Matching

In this lesson we'll learn how to exit a program using the `std::process` module in Rust and it's `exit()` method.

This lesson shows how to use a Rust `loop` to run a program infinitely.

Create a loop in Rust

This lesson takes an existing function with duplicated functionality and makes it more DRY by extracting core functionalities into another function.

This lesson explains **Type Inference** in Rust and how it allows the compiler to figure out by itself, what type variables have when they get their values assigned.

There are cases when the compiler cannot infer a value's type through static analysis. In such cases, developers have to provide type annotations explicitly.
