Understand it, then run it
Clippy is a tool that checks your Rust code for common mistakes and style issues. A feature freeze means that for a set period no new checks will be added. The freeze lasts 12 weeks, from the beta of Rust 1.89.0 on June 26 2025 to the stable release on September 18 2025. During that time Clippy will only receive bug fixes, so the checks you see will become more reliable.
Run it now
// This program demonstrates the Clippy feature freeze announcement.
// It simply prints a message about the freeze period.
// The output is deterministic and does not rely on any Clippy internals.
fn main() {
// The Clippy project will be on feature-freeze for 12 weeks,
// from Rust 1.89.0 beta (June 26 2025) to Rust 1.89.0 stable (September 18 2025).
println!("Clippy feature freeze: no new lints until September 18 2025.");
}
What it printed when we ran it on Rust 1.98.1 (edition 2024)
Clippy feature freeze: no new lints until September 18 2025.
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.
