What’s an actual use case for Rust

This page summarizes the projects mentioned and recommended in the original post on reddit.com/r/rust

Our great sponsors
  • ONLYOFFICE ONLYOFFICE Docs — document collaboration in your environment
  • CodiumAI - TestGPT | Generating meaningful tests for busy devs
  • InfluxDB - Access the most powerful time series database as a service
  • SonarLint - Clean code begins in your IDE with SonarLint
  • flyctl

    Command line tools for fly.io services

    - heavily used in for all kinds of network backend stuff, eg. at AWS, fly.io, Deno, even Cloudflare I think (don't they use deno deploy for some of their stuff?), Discord, Microsoft

  • veloren

    Games (Veloren, or check out this website for updates on other games being developed in Rust)

  • ONLYOFFICE

    ONLYOFFICE Docs — document collaboration in your environment. Powerful document editing and collaboration in your app or environment. Ultimate security, API and 30+ ready connectors, SaaS or on-premises

  • tauri

    Build smaller, faster, and more secure desktop applications with a web frontend.

    You can release any desktop application with web UI (Electron-style) using Tauri, here are some showcases

  • axum

    Ergonomic and modular web framework built with Tokio, Tower, and Hyper

    Web applications e.g. online chess, or anything from this showcase list for axum or any other web framework for Rust you could find (e.g. Actix and its showcase list)

  • surrealdb

    A scalable, distributed, collaborative, document-graph database, for the realtime web

    Databases (SurrealDB)

  • gitoxide

    An idiomatic, lean, fast & safe pure Rust implementation of Git

    There's a re-implementation of git called gitoxide

  • rustdesk

    Virtual / remote desktop infrastructure for everyone! Open source TeamViewer / Citrix alternative.

    Remote Desktop (RustDesk)

  • CodiumAI

    TestGPT | Generating meaningful tests for busy devs. Get non-trivial tests (and trivial, too!) suggested right inside your IDE, so you can code smart, create more value, and stay confident when you push.

  • astro

    A fun safe language for rapid prototyping and high performance applications (by astrolang)

    Some people tried using Rust to implement programming languages, right now I do not know any bigger language with compiler written in Rust but there was an attempt with astro. Match statements make parsing in Rust pretty comfortable.

  • backend-lishuuro

    Backend code for lishuuro.

    Web applications e.g. online chess, or anything from this showcase list for axum or any other web framework for Rust you could find (e.g. Actix and its showcase list)

  • lapce

    Lightning-fast and Powerful Code Editor written in Rust

    IDEs (lapce)

  • Fyrox

    3D and 2D game engine written in Rust

    Game engines (Bevy, Fyrox)

  • evcxr

    In theory you should be able to create Rust notebooks (Jupyter notebook) using evcxr so maybe some AI, data analysis, prototyping make sense if you aim for good performance in final application (protype in evcxr and use notebook as reference to implement final application in Rust for speed and safety).

  • embassy

    Modern embedded framework, using Rust and async.

    Embedded (getting examples is starting to get tiring, so here you have just a lightweight alternative for some of RTOS applications which do not have hard real time constraints)

  • bevy

    A refreshingly simple data-driven game engine built in Rust

    Game engines (Bevy, Fyrox)

  • InfluxDB

    Access the most powerful time series database as a service. Ingest, store, & analyze all types of time series data in a fully-managed, purpose-built database. Keep data forever with low-cost storage and superior data compression.
