tff.types.StructType

An implementation of tff.Type representing structural types in TFF.

Inherits From: Struct, Type

tff.types.StructType(
    elements: Iterable[object], *, convert: bool = True
)

Elements initialized by name can be accessed as foo.name, and otherwise by index, foo[index].

elements An iterable of element specifications. Each element specification is either a type spec (an instance of tff.Type or something convertible to it via tff.types.to_type) for the element, or a (name, spec) for elements that have defined names. Alternatively, one can supply here an instance of collections.OrderedDict mapping element names to their types (or things that are convertible to types).
convert A flag to determine if the elements should be converted using tff.types.to_type or not.
