build: declare Rust 1.92 as the MSRV and check it in CI
rust-version = "1.92" in [workspace.package], inherited by every crate.
1.92 is the floor: wgpu (clawhdf5-gpu) requires it, and the whole
workspace, Python bindings included, checks cleanly on it. ci-test.sh
reads the version from Cargo.toml and checks the workspace on exactly
that toolchain, so the manifests and the README badge cannot drift from
what actually builds. The badge said 1.75, below edition 2024's own
floor.

clawhdf5-format

crates.io docs.rs

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_std support (disable std feature)
  • 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());
