Tutorial

A guided tour of the rustfits API. The Quickstart page covers the essentials in a single read; the topic pages go deeper on images, tables, compression, and headers.

If you already know astropy or fitsio, the surface here will feel familiar — FITS opens a file, fits[i] returns an HDU, and the HDU exposes read / write plus __getitem__ / __setitem__ for slicing. The differences are mostly in the details: structured compression configs, explicit var_dtypes= for variable-length table columns, and a single FITSHeader view that re-parses cards on every access rather than caching parsed values.
