read_superblock_extension_in, cache_image_state_in, CacheImage::decode_in and CacheImage::block_in take &dyn Storage (whose length is the end of file); the image block is one bounded read. The &[u8] functions are wrappers; applying an image in place still needs the bytes in memory. New test: extension messages, a cache image and a corrupt one decode to the same results through a read_at-only CountingStorage. Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>

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());
