In this liveProject, you’ll use some of the unique and lesser-known features of the Rust language to finish a prototype of a FinTech command line tool. You’ll step into the shoes of a developer working for Future Finance Labs, an exciting startup that’s aiming to disrupt mortgages, and help out with building its market-tracking backend. Your CTO has laid out the requirements for the minimum viable product, which must quickly process large amounts of stock pricing data and calculate key financial metrics in real time.

These projects are designed for learning purposes and are not complete, production-ready applications or solutions.

Manning author Claus Matzinger shares what he likes about the Manning liveProject platform

here's what's included

Project 1 Data Streaming with Async Rust
In this liveProject, you will complete a half-finished prototype tool designed to improve risk management in fund strategies. You’ll transform the existing code to use async programming, use concurrent requests to fetch and process data for the tool, and output data on the command line in a CSV format. Once you’ve built the basics, you’ll upgrade the CLI’s performance to concurrently fetch stock data every 30 seconds.
Project 2 Advanced Data Streaming with Async Rust
In this liveProject, you’ll implement the capability for your CLI tool to continuously poll the data source to create a stream of data over the command line. Once you’ve set up that functionality, you’ll integrate your new CLI into your company’s wider intelligence gathering system, which requires exposing an HTTP endpoint that provides the most recent performance indicators.

This liveProject is for intermediate Rust programmers who want to advance their knowledge beyond the basics. To begin this liveProject you will need to be familiar with the following:

  • Intermediate Rust, min. version 1.51
  • Basics of Cargo
  • Basics of Data processing
  • Basics of Concurrency

you will learn

In this liveProject, you’ll learn how to use unique features of the Rust ecosystem to write asynchronous code and build cross-platform applications. The skills you learn can be easily transferred to other large-scale and enterprise Rust development projects.

  • Async programming using different approaches
  • Use async streams for improved efficiency
  • Unit tests in async environments
  • Try out and implement advanced architectural styles for your code


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