wtf is pixiv-isucon2016-rust?

This repository is a Rust implementation of a web application built for an internal programming competition held by Pixiv, the Japanese illustration platform. The competition, called ISUCON, challenges teams to make a given web app run as fast as possible. This project is essentially a practice problem: it gives you a working version of a social image-sharing site, and your goal is to optimize its performance. At a high level, the application mimics a service where users can post images, view them, and interact with them. The implementation here is written in Rust, a programming language known for its speed and memory safety. The setup instructions indicate you would place this code within the larger structure of the competition's provided files. From there, you compile the code using Cargo, Rust's standard build tool, to produce a runnable web server. This project would be used by developers who want to practice performance tuning. In a competition setting, you start with a baseline application and then iteratively change the code or the database to handle more requests per second. Someone might use this specific version to see how a Rust implementation performs out of the box, or to practice optimizing an app written in a language that is already quite fast. The README notes that it does not fully implement all the features of other reference versions, so it is best treated as a starting point for experimentation rather than a complete, production-ready clone of Pixiv. The notable aspect of this project is the choice of Rust for a performance competition. Since the goal is to maximize speed, starting with an efficient, compiled language is an interesting approach. However, the README is sparse and only covers the initial setup and build process. It does not go into detail about the application's architecture, its dependencies, or how to run the accompanying benchmarking tools.
