Crate atfits_rs 

atfits-rs — shared low-level cfitsio helpers for the at*-rs FITS tools (fitscube-rs, convolve-rs, …).

These are the project-agnostic mechanics that every tool needs and that are easy to get subtly wrong against cfitsio:

• PixelType / CubeElem — precision + monomorphic section I/O.
• keys — update-in-place keyword editing (ffuky*, not the duplicating ffpky*) and convenience readers.
• header — HeaderGeom and WCS find_target_axis lookup.
• image — image-HDU creation/resize and header-only copying, including create_cube_open (the single-open-handle pattern that avoids a doubled zero-fill pass on close).
• mem_header — build a cube header in memory (create_mem_cube) and serialise it (extract_header_layout) so a tool can write the data unit with raw I/O and skip cfitsio’s zero-fill entirely.
• output_path — output-path construction.

Domain logic (beams, combine/extract, convolution, spectral specs) stays in the individual crates.

Modules

error

Error type shared by the low-level cfitsio helpers.

header

Header geometry and WCS axis lookup.

image

Image-HDU creation, resizing, and header-only copying.

keys

Raw cfitsio header keyword editing and reading.

mem_header

Build a cube’s FITS header without touching disk, so the data unit is never zero-filled by cfitsio.

path

Output-path construction helpers.

pixel

Pixel precision and monomorphic cfitsio section I/O.
