Understand it, then run it

// This program demonstrates that Cargo 1.92 has a new build‑directory layout.
// It does not compile a project, but it prints the path that Cargo would use
// for intermediate artifacts on a recent release. The path format is
// target/build/<hash>/deps, where <hash> is a unique identifier for the
// build unit. This change is internal to Cargo and does not affect
// standard library usage.
fn main() {
// Simulate the hash that Cargo would generate for a simple project.
let build_hash = "e3b0c442";
let path = format!("target/build/{}/deps", build_hash);
println!("Cargo 1.92 build directory layout: {}", path);
}
What it printed when we ran it on Rust 1.98.1 (edition 2024)
Cargo 1.92 build directory layout: target/build/e3b0c442/deps
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.
