We are very pleased to announce official Rust language support when you test your project on Travis CI.

This is available for both open source and private repositories right now.

For a while now we have seen the rise of developers testing Rust projects on Travis CI, usually by installing Rust and Cargo as required, and then running cargo build and cargo test .

With the awesome help of dyrim, who was very kind to send us a Pull Request to wrap these defaults, including the installation of Rust and Cargo, all you need to do is add:

language: rust

to your .travis.yml file and you are good to go!

By default this will test your project by installing Rust and Cargo nightly binaries. If you need a specific version, all you need to do is add the following to your .travis.yml :

language: rust rust: 0.11.0

and BOOM!, you are now testing against version 0.11.0 of Rust.

But what if you want to test against 0.11.0 and nightly?

language: rust rust: - 0.11.0 - nightly

We can hear you right now screaming ‘How delightful!’, but that’s not all!

As always you get all the awesome power of Travis CI, including the ability to override the install and script steps.

For example, if you don’t want Travis CI to run cargo build and cargo test , all you need to do is change your .travis.yml file to:

language: rust script: ./run_my_favourite_script

We have added full documentation on our Rust support in case you have any further questions.

Have a fantastic Tuesday,

The Travis CI Team
