// This program demonstrates the runner version requirement for actions/checkout v5.
// It simply prints a message; the real change is in the GitHub Actions runner,
// not in Rust code, so we just illustrate the concept here.
fn main() {
println!("If you run GitHub Actions with actions/[email protected], ensure your runner is at least v2.327.1.");
}
What it printed when we ran it on Rust 1.98.1 (edition 2024)
If you run GitHub Actions with actions/[email protected], ensure your runner is at least v2.327.1.
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.
