Understand it, then run it

The Rust team is testing a new version of the crates.io website. They are moving from the old Ember.js framework to Svelte 5. The new Svelte app is available at https://crates.io/svelte/. You can use it the same way you use the old site; no login is needed.

Run it now

Todayrust
// This program simply demonstrates that the Rust toolchain is available.
// It does not interact with the crates.io frontend, which is a web change.
fn main() {
    println!("The new crates.io Svelte frontend is now publicly testable at https://crates.io/svelte/");
}

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

The new crates.io Svelte frontend is now publicly testable at https://crates.io/svelte/

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.
