While Travis CI has built-in rust support in their infrastructure, it only supports linux builds. I wanted some CI for windows builds of Rust, so I created some configuration and install scripts for AppVeyor. I thought some other folks might be interested in the scripts and configuration template, so I cleaned it up and documented it and put it up on GitHub.
If anyone wants to get started using AppVeyor for Rust projects, the Rust install script and appveyor template configuration are at https://github.com/starkat99/appveyor-rust/
