Description:

 """ Dict representation of Structure. Args: verbosity (int):
 Verbosity level. Default of 1 includes both direct and cartesian coordinates for all sites, lattice parameters, etc. Useful for reading and for insertion into a database. Set to 0 for an extremely lightweight version that only includes sufficient information to reconstruct the object. fmt (str):
 Specifies a format for the dict. Defaults to None, which is the default format used in pymatgen. Other options include "abivars". **kwargs: Allow passing of other kwargs needed for certain formats, e.g., "abivars". Returns: JSON serializable dict representation. """
