WithFunctionalLocalState

class penzai.deprecated.v1.data_effects.local_state.WithFunctionalLocalState

Bases: EffectHandler

LocalState effect handler that functionalizes local states.

WithFunctionalLocalState transforms the body layer so that it takes a dictionary of states as an argument and returns a dictionary of states as a result.

The standard way to construct a WithFunctionalLocalState handler is to use handle_local_states, which returns a functional wrapper and also the initial state callable. Conversely, you can re-embed local states into the model using freeze_local_states.
