clawhdf5

crates.io docs.rs

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();
