Course details
Rust is an extremely powerful and often intimidating language, but it’s particularly well-suited for web services. In this course, instructor Tim McNamara shows you how to get started building and deploying web services written in Rust. Learn how to use the Actix Web framework to create a service that can receive a payload via an HTTP POST request, process it and return JSON. Along the way, you’ll also explore the essentials of stateful endpoints, monitoring and observability, telemetry, testing, deployment, and much more.
