Rust Packaging Tutorial

With the growing popularity of Rust as a programming language, especially for writing powerful command-line applications, GUI applications using the powerful GTK bindings, and even web services, more and more of those projects are getting packaged for Fedora. The Rust SIG continues to maintain and improve tools which makes creating new packages for Rust crates and their ongoing maintenance as streamlined as possible.

This workshop includes:

* introduction to Rust packaging: how cargo concepts map to RPM concepts; contents and structure of RPM packages of Rust library crates and applications; why we don't use vendored dependencies
* introduction to using rust2rpm: using it to create an initial package for a Rust library crate or application; updating an existing library; adding a compatibility package for an older version of an existing Rust library package; upcoming improvements that will make packaging Rust crates even easier
* introduction to troubleshooting: how to spot missing or outdated dependencies; how to interpret and fix build failures; how to fix or work around failures in a crate's test suite
* "live demo": updating real Fedora Rust packages (possibly one "simple" case and one more "complicated" case); initializing a new Rust package (probably only a "simple" case without missing dependencies, depending on time available)

This should give attendees a good starting point if they want to package their favourite new Rust application, or if they want to help with maintenance of the Rust stack in Fedora.
