BTreeV1Node::parse_in reads a node's header and then its keys and children, two bounded reads; collect_symbol_table_nodes_in walks the tree over any Storage. The &[u8] functions are wrappers. New test: nodes with siblings and 4- and 8-byte offsets cut at every length, and a two-level tree with truncated leaves, give identical results through a read_at-only CountingStorage (six reads for the three nodes).

clawhdf5-format
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());
