Cast fixed-length string -> std::string

Hey.

Thanks for replying. I think my comment here best describes my problem: #94 (comment). Looking through the document, I cannot find a way to construct |
I think the problem here is that Therefore,
works but
doesn't. |
Oh, I'm sorry I overlooked the fact that the signature of FixedLenStringArray is |
I'll try to look into this in my free time. For now, I will simply set |
@JATC1024 You probably have a good reason to do what you do. Still, auto mystring = H5Easy::load<std::string>(file, "/path/to/my/string"); Also, unlike @ferdonline I'm not super sure that a 'fixed-size' string object that is dynamically allocated is relevant. Wouldn't that we |
@tdegeus
For variable-length strings, this works. For fixed-length strings, it shows the error Or are you suggesting that I can load each string in the array individually? Something like
I see you do have a function like that. I will try it tomorrow, though I think I will get the same error. |
Thanks for the clarification @JATC1024 . This makes a lot of sense. I should say that I'm not at all an expert on HDF5 fixed-length strings. That being said, I see no reason why |
Shall we rename this issue (or open a new one) indicating that it is more than missing conversion from fixed-length strings to |
@tdegeus sure, whatever way you see fit. If you create a new one then I think we can close this one. |
std::string
missing
With #744 merged std::strings and containers thereof, e.g. std::vectorstd::string can be read and written to fixed or variable length HDF5 strings. There's an example here: |
Is your feature request related to a problem? Please describe.
H5Easy.load cannot load fixed length strings. I always get the error
Can't output std::string as fixed-length. Use raw arrays or FixedLenStringArray
. I tried to useHighFive::FixedLenStringArray<N>
and it worked. However, I had to know the length of the strings beforehand since N must be a constant. This does not seem viable to me.Describe the solution you'd like
Something like
would be nice. Or even better if
H5Easy
will handle everything so that I don't have to care if the dataset is fixed length or not.The text was updated successfully, but these errors were encountered:
