Understand it, then run it

This Week in Rust 637 announced the first look at 2026 Project goals and highlighted the crate *vortex*, a Linux‑only io_uring‑based BitTorrent library and TUI. It also listed several tooling releases such as Eurydice, kinded, CGP, and hotpath‑rs. The newsletter does not describe any language or library change that affects your code.

// This program demonstrates that nothing in this newsletter changes the Rust language.
// It simply prints a message confirming that the current edition (2024) remains unchanged.
fn main() {
    println!("Rust 1.98.1 (edition 2024) is still the same as before.");
}

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

Rust 1.98.1 (edition 2024) is still the same as before.

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.
