Building Cloudflare Images in Rust and Cloudflare Workers

What this post added

This post details the technical implementation of Cloudflare Images and Image Resizing, highlighting the use of Rust for reusable libraries and Cloudflare Workers for edge processing. It covers the architecture of image transformations, storage mechanisms (including Quicksilver for variant definitions and URL-based metadata), cache purging strategies (by URL and tag), and URL signing for access control. Direct creator uploads are supported via Workers KV. Future work includes resizing hints on upload and serving images from custom domains.
