FITS encoder and decoder in Rust

fits-rs

FITS encoder and decoder in Rust.

Make sure to check out the documentation of this crate. The build can be followed as well. The coverage report is provided by coveralls.

FITS

The Flexible Image Transport System (FITS) is

an open standard defining a digital file format useful for storage, transmission and processing of scientific and other images.

The reference documentation on the FITS standard can be found an NASA's FITS pages. You can get a copy by executing the following command:

wget --output-document=fits-reference.pdf "https://www.aanda.org/articles/aa/pdf/2010/16/aa15362-10.pdf"

Reading Primary Header

Even though the headers of FITS files are in ASCII, you can use this crate to read the primary header.

    let args: Vec<String> = env::args().collect();
    let filename = &args[1];
    let header_index = u64::from_str(&args[2]).expect("should be a non-negative number");

    let mut f = File::open(filename).expect("file not found");
    let mut buffer: Vec<u8> = vec!();
    let _ = f.read_to_end(&mut buffer);

    let result = fits(&buffer);

    match result {
        IResult::Done(_, trappist1) => {
            let header: &Header = if header_index = 0 {
                &trappist1.primary_hdu.header
            } else {
                &trappist1.extensions[header_index].header
            }

            for record in header.keyword_records {
                println!("{:?}", record);
            }
        },
        _ => panic!("Whoops, something went wrong")
    }

You can find this binary in src/bin/headers.rs.

Unfortunately, some extensions are in binary.

fits-rs's Issues

Make use of docs.rs

This basically means removing the deployment to GitHub pages. This frees up that address to go into some examples, or tutorials

Report test coverage with coveralls

I want to have more metrics about the fits-rs project. Coveralls seems a nice service.

cargo-travis looks like to have our options covered.

Please add examples

Hello. Can you please add an examples directory of how to use this API? Because you have a Fits struct and you also return a IResult which is an impl that wraps Result I think there is alot of confusing stuff happening and it is difficult to make this work. Your help is greatly appreciated.

Issue parsing most fits files

This package seems to be tightly coupled to the example file:
k2-trappist1-unofficial-tpf-long-cadence.fits

And cannot parse most other fits files that have been passed to it. Dies with the following error: Tag

How to get data

Hello. How does one go about getting the data out of the parsed packet? It's a private field and there is no evidence of a getter method. Help?
