Understand it, then run it

The weekly highlight is the crate flac-codec, which implements the Free Lossless Audio Codec (FLAC) file format. If you want to work with FLAC files in Rust, this crate is the go‑to library for that task. It is not part of the standard library, so you need to add it to your Cargo.toml to use it. The change is simply that the Rust community is recommending this crate for anyone needing FLAC support.

Run it now

Todayrust

// This program demonstrates how to add the flac-codec crate to a project.
// Since flac-codec is not part of the standard library, we simply print a
// message indicating its presence. In a real project, you would add
// flac-codec to Cargo.toml and use its API to read or write FLAC files.

fn main() {
    println!("flac-codec is the crate of the week for FLAC support.");
}

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

flac-codec is the crate of the week for FLAC support.

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.
