Discussion on Hacker News.
This project demonstrates a complete, albeit simple, example of integrating Rust code into a web application. This is accomplished by compiling Rust to asm.js or WebAssembly. The basic design pattern this project explores uses Rust to implement CPU bound portions of an app while using existing web technologies to handle user facing, I/O bound pieces. The guide explores this design pattern in detail.
The project compares implementations of the k-means clustering algorithm (this example's CPU bound task) applied to an image. The algorithm gives the resulting image a softened, painted look.
See the guide for steps on installing the dependencies.
From the top level of the project run
cargo run --release
The resulting painted image can be found at img/out.jpg.
