Range-read milestone M1, first step (docs/design/range-reads.md §3(a)): a synchronous, no_std read interface with u64 offsets, read_at returning Cow<[u8]>, read_ranges, len and an as_contiguous fast path. Implemented for [u8], Vec<u8>, &T, Box<T> and Arc<T>; slices serve borrowed bytes. read_exact_at reproduces the parsers' UnexpectedEof bounds error exactly, so converted modules keep their error values. FormatError gains Storage(String) and ContiguousStorageRequired; it and the facade Error are now #[non_exhaustive] (breaking for exhaustive matches, noted in the changelog; the Python bindings' match gets a wildcard arm).

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();
