Struct Json 

pub struct Json { /* private fields */ }

JSON backend

All data is saved in JSON files inside json_folder. The session information is stored directly there with its runs id as filename. This id is also used to create a subfolder where all datasets are stored. For those, the id is used as a filename.

A folder with one session and five datasets could look like this:

9F03105D9451CC3A.json
9F03105D9451CC3A
9F03105D9451CC3A/96ae94e6-cc1a-4621-999c-32a72741e4e8.json
