Is there any part of the Standard Library that really impresses you?

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

Our great sponsors
  • InfluxDB - Collect and Analyze Billions of Data Points in Real Time
  • Onboard AI - Learn any GitHub repo in 59 seconds
  • SonarLint - Clean code begins in your IDE with SonarLint
  • Revelo Payroll - Free Global Payroll designed for tech teams
  • rust

    Empowering everyone to build reliable and efficient software.

    That article is a few years old though if you try to follow any real links, if you want to read the current code it is in the alloc crate and is of course wonderfully commented.

  • rfcs

    RFCs for changes to Rust

    Rust did at one time have a green-threading model which required a rather heavyweight runtime; the background on the green-threading model and the reasons it were removed are outlined in RFC 230.

  • InfluxDB

    Collect and Analyze Billions of Data Points in Real Time. Manage all types of time series data in a single, purpose-built database. Run at any scale in any environment in the cloud, on-premises, or at the edge.

  • flume

    A safe and fast multi-producer, multi-consumer channel. (by zesterer)

    I also like flume, it has impressive performance (although not the best). More importantly, it's written only with safe rust.

  • stdx

    The missing batteries of Rust

    brson had a repository called and it's a pity it isn't maintained anymore: some of them are in disuse now (for example, instead of lazy_static prefer stdlib's Lazy, or better yet, you don't need them if you just want to initialize a mutex or something; also error-chain) and the list could use some maintenance

  • postfix-macros

    Postfix macros on stable Rust, today.

    There is a macro that enables postfix macros (it also links to an RFC on the subject):

  • Onboard AI

    Learn any GitHub repo in 59 seconds. Onboard AI learns any GitHub repo in minutes and lets you chat with it to locate functionality, understand different parts, and generate new code. Use it for free at
