The first step, called Format Check, is a Command Line that runs Custom script with a single command: cargo fmt -- --check. This command will check the style of the code with the rustfmt tool. Add the next build step, called Build (you can use your own name), with the cargo build command:

Now, if you click the Build Steps menu item, you will see the steps we created:

Now you can start this building process by clicking the Run button, as shown in the preceding screenshot. It will immediately start building with the agent container.
