OxiH5 0.2.1 adds DEFLATE compression on write, per-chunk tiling, in-place dataset overwrite, and nested groups — and fixes 9 correctness bugs, including a chunk B-tree defect that made every chunked dataset the writer produced unreadable by libhdf5. 682 tests passing — the sovereign scientific-data layer for COOLJAPAN.
OxiH5 0.2.0 adds superblock v1 parsing, v2/v3 superblock-extension decoding (B-tree K values, shared message table, file space info, driver info), and fixes a silent OCHK object-header creation-order misdecode. 494 tests passing across four crates — the sovereign scientific-data layer for the COOLJAPAN ecosystem.
OxiH5 0.1.4, the COOLJAPAN Pure-Rust HDF5 reader, adds Virtual Dataset (VDS) resolution, chunked variable-length dataset reads, szip RAW-mode chunk decoding, and soft-link-to-external-link chains, plus a fix for a silently mis-decoded global-heap reference. 486 tests passing across four crates — the sovereign scientific-data layer for the COOLJAPAN ecosystem.
OxiH5 is the COOLJAPAN Pure-Rust HDF5 reader — it parses real HDF5 files written by h5py and libhdf5 from raw bytes, with no hdf5-sys, no C libhdf5, and no unsafe in production paths. All 11 datatype classes, every chunk index, deflate/shuffle/fletcher32/szip/nbit/scaleoffset filters, mmap, and a NetCDF-4 reader on top — part of the NoFFI sovereign Rust stack.
