Struct tract_tensorflow::tfpb::tensorflow::StructuredValue

pub struct StructuredValue {
    pub kind: Option<Kind>,
}

StructuredValue represents a dynamically typed value representing various data structures that are inspired by Python data structures typically used in TensorFlow functions as inputs and outputs.

For example when saving a Layer there may be a training argument. If the user passes a boolean True/False, that switches between two concrete TensorFlow functions. In order to switch between them in the same way after loading the SavedModel, we need to represent “True” and “False”.

A more advanced example might be a function which takes a list of dictionaries mapping from strings to Tensors. In order to map from user-specified arguments [{"a": tf.constant(1.)}, {"q": tf.constant(3.)}] after load to the right saved TensorFlow function, we need to represent the nested structure and the strings, recording that we have a trace for anything matching [{"a": tf.TensorSpec(None, tf.float32)}, {"q": tf.TensorSpec([], tf.float64)}] as an example.

Likewise functions may return nested structures of Tensors, for example returning a dictionary mapping from strings to Tensors. In order for the loaded function to return the same structure we need to serialize it.

This is an ergonomic aid for working with loaded SavedModels, not a promise to serialize all possible function signatures. For example we do not expect to pickle generic Python objects, and ideally we’d stay language-agnostic.
