Understand it, then run it

Todayrust
// This program demonstrates that the Rust code itself is unaffected by the
// actions/checkout version bump. It simply prints a message.
fn main() {
    println!("Checkout action updated to v6; Rust code unchanged.");
}

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

Checkout action updated to v6; Rust code unchanged.

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.
