tff.structure.update_struct

Constructs a new structure with new values for fields in kwargs.

tff.structure.update_struct(
    structure, **kwargs
)

This is a helper method for working structured objects in a functional manner. This method will create a new structure where the fields named by keys in kwargs replaced with the associated values.

Note: _This method only works on the first level of structure, and does not recurse in the case of nested structures. A field that is itself a structure can be replaced with another structure.

Args
structure	_The structure with named fields to update.
**kwargs	_The list of key-value pairs of fields to update in structure.

Returns
A new instance of the same type of structure, with the fields named in the keys of **kwargs replaced with the associated values.

Raises
KeyError	If kwargs contains a field that is not in structure.
TypeError	If structure is not a structure with named fields.
