open(bytes) -> H5File with kind/list/info/attrs/attrErrors/read/ readHyperslab. Numeric data comes back in the typed array of the stored width (Int16Array for i16, BigInt64Array for i64, Float32Array for f32/f16, ...), strings and enum names as string arrays, array datatypes flattened with their dims appended to the shape. Compound, reference, opaque and VL-sequence datasets are refused with an error naming the type; nothing is returned as reinterpreted bytes. The logic is in a plain-Rust core module, tested natively: unit tests, and h5py_interop, which compares every dataset, hyperslab, listing and attribute of an h5py- and a netCDF4-written file with what libhdf5 reads back (generator shared with the Node test of the built package). No mmap, no threads; lz4 is on, zstd/szip (C) are not. A wasm-release profile (opt-level s, LTO) serves the browser build. ci-test.sh lints the crate for wasm32 and checks it builds no C.
