Understand it, then run it

The triagebot is a tool that helps keep the Rust repository clean by automatically closing or labeling pull requests that are no longer needed. A new feature lets the bot show the *range‑diff* of a pull request, meaning it can display only the parts of the code that changed. This is useful when a pull request is force‑pushed or rebased, because the bot can still understand what was added or removed. The change was merged on September 22 2025 and is now available to use.

Run it now

Todayrust
// This program demonstrates the range‑diff feature of the triagebot.
// It is a placeholder because the feature is not part of the standard library.
// In a real setup, you would call the triagebot API with the `--range-diff` flag.
fn main() {
    println!("Range‑diff feature is now available in the triagebot as of Sep 22 2025.");
}

What it printed when we ran it on Rust 1.98.1 (edition 2024)

Range‑diff feature is now available in the triagebot as of Sep 22 2025.

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
