Testumgebung

The Rust Playground provides an easy way to run short Rust programs, and is the basis for the examples and exercises in this course. Try running the “hello-world” program it starts with. It comes with a few handy features:

  • Under “Tools”, use the rustfmt option to format your code in the “standard” way.

  • Rust has two main “profiles” for generating code: Debug (extra runtime checks, less optimization) and Release (fewer runtime checks, lots of optimization). These are accessible under “Debug” at the top.

  • If you’re interested, use “ASM” under “
” to see the generated assembly code.

Speaker Notes

 This slide should take about 2 minutes.

As students head into the break, encourage them to open up the playground and experiment a little. Encourage them to keep the tab open and try things out during the rest of the course. This is particularly helpful for advanced students who want to know more about Rust’s optimizations or generated assembly.
