- clippy --all-targets plus a clawhdf5-format feature matrix (parallel, lz4, zstd, pcodec, fast-checksum); fix the accumulated lint backlog in test, bench and feature-gated code (no behaviour changes). - Install python3 + h5py/numpy/netCDF4/xarray in the CI container and set CLAWHDF5_REQUIRE_INTEROP=1, which makes a missing interop dependency a test failure. Every h5py/netCDF4 interop test used to skip silently in CI. Run the #[ignore]d writer_h5py_tests suite explicitly. - cargo bench --no-run so benches can't rot; fix bench.rs and memory_bench.rs, which no longer compiled against the current strategy/consolidation APIs. - Optional fuzz smoke run via CLAWHDF5_FUZZ_SECONDS. - CHANGELOG and docs/known-issues.md updated.

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 (
mmapfeature, enabled by default) - Parallel chunk reads via Rayon (
parallelfeature) - 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();
