rfitsio

Pure Rust implementation of CFITSIO — a library for reading and writing FITS files used in astronomical data storage.

Status

Early-stage / experimental. Intended for developers and testing, with no external dependencies.

Usage

[dependencies]
rfitsio = "0.3.0"

use rfitsio::{FITSFile, HDU};

let mut file = FITSFile::new();
let mut hdu = HDU::init();
hdu.add_header("SIMPLE", "T");
hdu.add_data(pixel_bytes);
file.add_hdu(hdu);
file.write_to_file("output.fits")?;

Features

• Build and serialize FITS files (HDU headers + image data)
• FITS-compliant 2880-byte block alignment
• Big-endian encoding/decoding helpers (rfitsio::endian)
• Basic FITS file parser
