// This program demonstrates the Cargo 1.93 development‑cycle announcement.
// It simply prints the version that the Rust team has released as the
// current development‑cycle package manager.
fn main() {
    // Cargo 1.93 is the latest development‑cycle version as of Jan. 7, 2026.
    println!("Cargo 1.93 is the current development‑cycle version.");
}

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

Cargo 1.93 is the current development‑cycle version.

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.
