Understand it, then run it

Rust 1.94.1 is a point release that fixes a few bugs that slipped into 1.94.0. The main fixes are to std::thread::spawn on the WebAssembly wasm32-wasip1-threads target, to some unstable methods on Windows file‑system options, and to Clippy’s match_same_arms lint. Cargo also had a couple of dependency updates to avoid certificate errors on FreeBSD and to patch a security issue in the tar crate. The release is available by running rustup update stable.

Run it now

Todayrust
// This program demonstrates that Rust 1.94.1 is available and compiles.
// It does not use any new API, because 1.94.1 only contains bug fixes.
fn main() {
    println!("Rust 1.94.1 is installed and running.");
}

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

Rust 1.94.1 is installed and running.

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.
