GlobalHeapCollection::parse_in / parse_index_in read the header, check the collection against the end of the file, and read the collection in one bounded read; objects are indexed in it with file offsets, as before. The &[u8] functions are wrappers. New test: collections with 4- and 8-byte lengths, one whose size runs past the file and one whose object overruns it, at two offsets and cut at every length, give identical results 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());
