Understand it, then run it

Run it now

// This program demonstrates the current state of the tooling mentioned in the newsletter.
// It does not compile until the new releases are available, so we show the problem it solves today.

fn main() {
    // Malai: share a dev server over P2P (currently not available in this sandbox)
    // println!("Running Malai server...");

    // Fluvio: streaming data analytics (we just print a placeholder)
    println!("Fluvio 0.17.2 would be used here for streaming data.");

    // Leptos: web framework (we just print a placeholder)
    println!("Leptos v0.8.0 would be used here for building web apps.");
}

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

Fluvio 0.17.2 would be used here for streaming data.
Leptos v0.8.0 would be used here for building web apps.

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.
