Function write_hdf5_file_image 

pub fn write_hdf5_file_image(
    datasets: &[Hdf5DatasetWrite<'_>],
    limits: Hdf5WriteLimits,
) -> Result<WrittenHdf5FileImage, Diagnostic>

Write a closed ordered set of primitive arrays into one complete HDF5 file image without granting filesystem or network authority.

Declaration order is non-semantic: datasets and derived groups are created in canonical path order. The Core VFD has backing storage disabled, object timestamps are disabled, datasets are fixed-size, contiguous, unfiltered, and use no attributes or committed datatypes. The output therefore lies in the exact subset accepted by crate::resolve_hdf5_file_image.

Errors

Returns EQ0811 for duplicate or over-budget declarations, invalid local conversions, native HDF5 failure, or an oversized output image.
