osobhandClaude Opus 5.5 2f252df084 fix(format): return whole VL sequences from read_vl_bytes

read_vl_bytes cut each element to the reference's length field, which
counts sequence elements, not bytes: a VL int32 [1, 2, 3] came back as
3 bytes. Return the whole global-heap object, which is element count x
base size bytes. No in-tree caller depended on the old behaviour.

clawhdf5

Pure-Rust HDF5 reader/writer — no C dependencies.

Features

Read and write HDF5 files entirely in Rust
Memory-mapped I/O for large files (mmap feature, enabled by default)
Parallel chunk reads via Rayon (parallel feature)
Lazy dataset access for minimal memory usage
h5py-compatible file output

Usage

use clawhdf5::File;

let file = File::open("data.h5").unwrap();
let dataset = file.dataset("/group/data").unwrap();
let values: Vec<f64> = dataset.read_1d().unwrap();
