Hi,
I am interested in using the SWMR feature of hdf5, but it seems that this is not (well) supported yet, I only found very few mentionings of "swmr" in the source code.

Extrapolating from the h5py example, I assume this flag would need to be passed when the file is opened. So perhaps the FileBuilder could be modified to support this?

Thanks for the insights, and for the continued support of hdf5 in rust!

SWMR is not supported by this crate yet, but should be possible to implement. It only needs a function for starting SWMR for the writer process and a flag for opening in SWMR mode. A PR is much appreciated!

thats what I thought, thanks for confirming
I am not 100% sure yet I will need the feature, but if I end up implementing it then I will make a PR
