class kauldron.metrics.EmptyState( *, parent: kauldron.metrics.base_state._MetricT = _EMPTY_TYPE.EMPTY, )[source]

Bases: kauldron.metrics.base_state.State[kauldron.metrics.base_state._MetricT]

Empty state.

classmethod empty() → kauldron.metrics.base_state.EmptyState[source]: Returns an empty instance (i.e. .merge(State.empty()) is a no-op).

merge( other: kauldron.metrics.base_state.EmptyState, ) → kauldron.metrics.base_state.EmptyState[source]

Returns a new state that is the accumulation of self and other.

Parameters:: other – A State whose intermediate values should be accumulated onto the values of self.
Returns:: A new State that accumulates the value from both self and other.

compute() → dict[Any, Any][source]: Computes final metrics from intermediate values.

replace(**updates): Returns a new object replacing the specified fields with new values.
