Crates.io: Development Update

Understand it, then run it

// This program demonstrates the crates.io update by printing a short message.
// The update itself does not affect Rust code, so we simply output the change.
fn main() {
    println!("Crates.io now offers a Code tab and independent usernames.");
}

Crates.io now offers a Code tab and independent usernames.

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.
