Network Applications using Tokio and Rust
Rust is undeniably syntax-heavy. After all, there’s a lot of intent to express, and Rust wants you to be explicit. Still, Rust is a very elegant language. This might not be so obvious at first, as Rust has borrowed elements from a lot of precursors that help you navigating when you start, but can be false friends in the long run, resulting in bloated code, unnecessary complexity, and hard-to-use APIs.
In this workshop, we’re going to learn what Rust has to offer to create code that is a delight to read and follow, easy to use, and plays along nicely with all the other libraries out there.
We learn about:
select! and join!Each chapter concludes with tasks for the audience.
Target audience: People with familiarity in Rust and basic networking (TCP, HTTP; knowing what a web-server does).
Expected workshop duration: full-day, 2-day

Using Websockets with Axum (examples within the Axum repo)
Oliver Gould from Buoyant on why Rust is a better choice for their tasks than Go. Oliver created Linkerd based on Rust and shows which parts of the language and Tokio excite them most.
