Understand it, then run it

Run it now

Todayrust
// This program demonstrates the idea of readiness gates and cert recycling
// in the kobe crate.  The kobe crate is not part of the standard library,
// so this code will compile only once kobe 0.35.0 is available in the
// dependency graph.  Until then, it simply prints a placeholder message.

fn main() {
    println!("Readiness gates and cert recycling are features of kobe 0.35.0.");
}

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

Readiness gates and cert recycling are features of kobe 0.35.0.

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.
