Crate of the week: Maycoon

Nice to knowecosystem

What changed: This week’s crate of the week is Maycoon, an experimental vello/wGPU‑based UI framework.
Production impact: The source does not say.
Try it: Add maycoon = "0.1" to your Cargo.toml and experiment with its API in a small UI demo.
Source: this-week-in-rust.org/blog/2025/04/23/this-week-in-rust-596/

Understand it, then run it

Maycoon is a crate that experiments with building user interfaces using the vello and wGPU graphics backends. It is not yet stable, so it is meant for developers who want to try new UI ideas or contribute to its development. The crate is highlighted in the weekly Rust newsletter, but the newsletter does not describe any new language feature. If you want to experiment, you can add maycoon to your Cargo.toml and start building simple widgets.

Run it now

Todayrust

// This program demonstrates that Maycoon is an experimental UI framework
// based on vello and wGPU.  It simply prints a message; the crate itself
// is not used here because it is not yet stable and not part of the
// standard library.

fn main() {
    println!("Maycoon: experimental vello/wGPU UI framework");
}

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

Maycoon: experimental vello/wGPU UI framework

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.
