Rust Infrastructure

Most services in the Rust Infrastructure are deployed via rust-central-station. Questions about infrastructure, including current status, should go to the #infra Discord channel.

Our stability guarantees: many of our services rely on publicly-accessible storage and APIs, but not all of these are intended for public consumption. At the moment, only the resources behind static.rust-lang.org are considered stable, meaning that those resources will not change without (at least) prior notice. If you are relying on other parts of the Rust project infrastructure for your own work, please let the infrastructure team know.

Highfive

Highfive is a bot (bot user account) which welcomes newcomers and assigns reviewers.

Rust Log Analyzer

The Rust Log Analyzer analyzes CI build logs to extract error messages and posts them to the pull request. It is run by TimNN.

Homu

Homu is a bot (bot user account) which manages pull requests. Approved pull requests are placed in a queue from which tests are run.

Documentation on homu commands can be found here.

Please contact Alex Crichton if something goes wrong with the bot.

rfcbot

rfcbot is a bot (bot user account) which helps manage async decision making on issues and PRs (typically RFCs). Team members can view any pending requests for review on the FCP dashboard.

Documentation on rfcbot commands can be found in the rfcbot repository.

rustbot

rustbot is a bot (bot user account) to assist with managing issues and PRs to allow users to label and assign without GitHub permissions. See the wiki for more information.

DXR

DXR is a cross-referenced source index for Rust, allowing the Rust source tree to be navigated and searched with ease. It is generated by rust-dxr

perf

perf offers information about the performance of rustc over time.

It is split into a data collector and a web frontend. The raw performance data is available here and can be browsed on the perf website.

One-off performance runs can done by addressing the rust-timer bot. On a PR, do a “try” build (@bors try), wait for it finish, then leave a comment with the merge commit hash like this:

@rust-timer build ac89e0324b48993d6d148f598ea0e7357e229c79

Rust Playground

Rust Playground allows you to experiment with Rust before you install it locally, or in any other case where you might not have the compiler available. The Rust playground can be accessed here.

Crater

Crater is a tool to run experiments across the whole Rust ecosystem. Its primary purpose is to detect regressions in the Rust compiler, and it does this by building large number of crates, running their test suites and comparing the results between two versions of the Rust compiler.

docs.rs

docs.rs builds and serves the rustdoc documentation for all crates on crates.io. Issues may be filed on the docs.rs repository. See the #docs-rs channel on Discord for discussion or urgent issues.

Toolstate

The state of tools included with Rust are tracked on the toolstate page. When each PR is merged via CI, the status of each tool is recorded in a JSON file and stored in the toolstate repo. For further information, see the toolstate system documentation.

Rustup components history

The rustup components history tracks the status of every rustup component for every platform over time. See the repository for more information.

CI Timing Tracker

The CI Timing Tracker tracks and compares how long CI jobs take over time. It is run by Alex Crichton.
