Crate fakejpeg 

“Fake” jpeg generator library for Rust

This library began as a port of Alun Jones’ fakejpeg Python library to Rust, using winnow for parsing, and with a focus on performance. Much like the original library, the generated images aren’t exactly correct, but they’re - usually - good enough that browsers, and a lot of image viewers display them nevertheless.

The main components of the library are Template and ImageGenerator: these can be used to parse JPEG images into a template, and to generate randomized fakes from said template, as many as you wish.

While a Template is expensive to build, an ImageGenerator isn’t: it borrows the template for generation purposes. As such, it is recommended to keep a Template around as long as possible - you’re free to create and drop ImageGenerators as needed, they’re not much more than a thin wrapper around the template.
