ExtensibleArrayHeader::parse_in reads the header in one read, and read_extensible_array_chunks_in reads each index block, super block and data block as a prefix read and then one window of the whole structure (paged data blocks included); checksums and elements are checked in the window with bounds errors reported as the whole-file checks did. The &[u8] functions are wrappers. New test: an array with inline elements and a data block, cut at every length and damaged in each structure, reads identically through a read_at-only CountingStorage.

Pure-Rust HDF5 binary format parsing and writing — no C dependencies.
Features
- Zero-copy superblock, object header, and B-tree parsing
- Chunked dataset read/write with filter pipelines
no_stdsupport (disablestdfeature)- Optional parallel reads via Rayon
- SHA-256 provenance tracking
Usage
use clawhdf5_format::Superblock;
let data = std::fs::read("data.h5").unwrap();
let sb = Superblock::from_bytes(&data).unwrap();
println!("HDF5 version {}.{}", sb.version_major(), sb.version_minor());
