HIDEFIX

A fast and concurrent reader for HDF5 and NetCDF (v4) files.

Currently requires Rust nightly.

This library allows a HDF5 file to be read in a multi-threaded and concurrent way. The chunks of a dataset need to be indexed in advance, this can be time-consuming, but efficient serialization and partially zero-copy deserialization through serde is implemented. In particular by storing the indexes in a fast database, like sled allows speedy access.

This allows multiple datasets (variables) to be read at the same time, or even different domains of the same dataset to be read at the same time.

The library is meant to be used in conjunction with the bindings to the official HDF5 library.

Usage

Create an index, then read the values:

use hidefix::idx::Index;
use hidefix::reader::Reader;

let indx = Index::index("tests/data/coads_climatology.nc4").unwrap();
let mut r = indx.reader("SST").unwrap();

let values = r.values::<f32>(None, None).unwrap();
println!("SST: {:?}", values);

It is also possible to stream the values. The streamer is currently optimized for streaming bytes.
