Crate spicekit 

Pure-Rust readers (and writer) for NASA/NAIF SPICE kernel formats.

Implements the subset of SPICE this crate explicitly supports — DAF containers, SPK ephemerides, binary PCK rotations, and the supported text-kernel subset (body names, LSK DELTET/*, and the Earth→ITRF93 frame association) — with memory-mapped I/O and no FFI. The DAF parser (daf) is the shared container reader; the per-kernel-type parsers (spk, pck, text_kernel) build on top of it. spk_writer emits SPK Type 3 and Type 9 segments.

This crate does not link CSPICE. Bit-for-bit parity against CSPICE is asserted in the sibling spicekit-bench crate, which links cspice-sys behind a feature flag and exercises every numeric code path (spkez, pxform, sxform, bodc2n, bodn2c, plus the supported text-kernel semantics) at machine-epsilon tolerance.
