HDF5 Direct Chunk Operations Wrapper

This module provides a high-level D wrapper for HDF5 Direct Chunk Operations. Direct chunk I/O allows reading and writing raw data chunks directly, bypassing the HDF5 filter pipeline. This is useful for applications that handle compression externally or need maximum I/O performance.

void appendToDataset(hid_t datasetId,  uint  axis,  size_t extension,
                      hid_t memtype,  const  void *  data,  hid_t dxpl =  H5P_DEFAULT)

Appends data to a chunked dataset along a specified dimension.

uint readChunk(hid_t datasetId,  const  hsize_t *  offset,  void *  buffer,
                hid_t dxpl =  H5P_DEFAULT)

Reads a raw data chunk directly from a chunked dataset.

uint readChunk(size_t N)(hid_t datasetId,  const  hsize_t[N]  offset,  void *  buffer,
                          hid_t dxpl =  H5P_DEFAULT)

Reads a raw data chunk directly from a chunked dataset (array overload).
