Understand it, then run it

Todayrust
// This program demonstrates that the crates.io Security tab feature is not yet part of Rust 1.98.1 (edition 2024).
// It simply prints a message explaining the current state.
fn main() {
    println!("The crates.io Security tab is a planned feature; it is not available in the current Rust release.");
}

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

The crates.io Security tab is a planned feature; it is not available in the current Rust release.

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.
