Look inside

You’re the star developer for Future Finance Labs, a fintech scaleup whose partner consultants are so happy with the prototype of an exchange platform you’ve built that some of them have brought a trading firm on board. Your task is to extend your prototype to include a platform for trading futures that the firm would like to offer its clients. You’ll lay the web project foundation by moving the Rust code for the existing matching engine to a shared library, adding a skeleton project for the web server, and creating a Cargo workspace. You’ll set up a warp web service to interact with the trading platform, add JSON serialization to your types, and use asynchronous Rust programming to create handler functions. Then you’ll upgrade the existing command line interface to connect with your new service instead of the local variant via REST. When you’re finished, you’ll have built a complete Rust HTTP API that will be a blueprint for additional Rust web services, small and large.

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

This liveProject is for enthusiastic Rust beginners who want to put their Rust skills and knowledge into practice. To begin these liveProjects you’ll need to be familiar with the following:

  • Basic Rust: declaring variables, loops, functions, branches, debugging (println!), modules, types (structs, enums)
  • Basic software engineering (unit testing, modularization, web API basics)
  • Basic finance: phrases and terms (for example, “signer” and “debit”)


You choose the schedule and decide how much time to invest as you build your project.
Project roadmap
Each project is divided into several achievable steps.
