Fetch-Data, a Pooch-compatible crate for downloading sample files

[CarlKCarlK]

Greetings,

Of possible interest, if you create scientific software for others with ndarray. Such software often refers to sample files. But how can your users get those sample files?

Python has the popular Pooch package for downloading sample files. I've created Fetch-Data for Rust. It uses the same registry format as Pooch. It only downloads files as needed and it checks their contents with a SHA256 hash.

The bed-reader genomics create uses ndarray internally and uses fetch-data to download samples files.
