Rust Essentials - Second Edition

Web development

A general overview of the status of this domain can be found at http://arewewebyet.com/. At the time of writing, a number of web frameworks that provide vital support for basic needs are available. To get an initial idea of coding in practice, we have supplied a "hello world" example snippet for each of them:

• iron is the oldest framework. It was built for high concurrency needs, so it scales very well. The codebase has a high degree of modularity. Here is how you say "hello-world" in iron:
