Look inside

Svalbard Inc.’s customers are reveling in the comfort of the global online store’s Scandinavian furniture. But, for Svalbard, the cost to scale its backend applications is less than comfortable. To ease its pain, the store has begun migrating its legacy mainframes to a more flexible, modern deployment model. Svalbard has already implemented a CLI tool that internal developers and operators can easily configure to their needs. As a Rust programmer, it’s up to you to improve this tool. You’ll track down potential performance bottlenecks with the help of flame graphs, then implement solutions to tackle them using hyper. You’ll verify the performance improvements, then create a tool for guarding against regressions with the Criterion suite. When you’re done, you’ll be comfortable evaluating and improving an asynchronous Rust application.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.

project author

Marco Amann

Marco Amann is a software engineer at AxonIQ where he develops robust distributed systems. He has leveraged Rust in both professional and personal endeavors to build applications spanning a wide range of areas. He has co-authored a German language book about Rust, and spoken at workshops and conferences on topics such as embedded Rust on an STM32 and making APIs safer by adhering to rules about borrowing.

This liveProject is for Rust programmers who are familiar with Rust syntax and its ownership system and who want to write reliable, efficient code. To begin these liveProjects you’ll need to be familiar with the following:

  • intermediate Rust
  • Cargo
  • CLIs
  • Your favorite IDE or editor
  • Basic knowledge of memory management
  • Basic knowledge of how the stack and the heap work

you will learn

In this liveProject, you’ll learn to evaluate and improve an asynchronous Rust application using tools in Rust's rich ecosystem.

  • Approach the same problem from multiple angles to ensure no false assumptions are made
  • Measure the performance of Rust applications
  • Analyze the runtime behavior of Rust applications
  • Use statistical benchmarking to ensure your proposed changes have the desired effect and that future changes do not introduce performance regressions


You choose the schedule and decide how much time to invest as you build your project.
