# EstimatorToTemporalAdaptor A temporal estimator wrapping an estimator. ``` struct EstimatorToTemporalAdaptor where Base : Estimator ``` ## Topics ### Creating the estimator [`init(Base)`](/documentation/CreateMLComponents/EstimatorToTemporalAdaptor/init(_:)) Creates a temporal estimator from an estimator. ### Encoding and decoding [`func encode(EstimatorToTemporalAdaptor.Transformer, to: inout any EstimatorEncoder) throws`](/documentation/CreateMLComponents/EstimatorToTemporalAdaptor/encode(_:to:)) Encodes a fitted transformer. [`func decode(from: inout any EstimatorDecoder) throws -> EstimatorToTemporalAdaptor.Transformer`](/documentation/CreateMLComponents/EstimatorToTemporalAdaptor/decode(from:)) Decodes the transformer. ### Fitting a transformer [`func fitted(to: InputSequence, eventHandler: EventHandler?) async throws -> EstimatorToTemporalAdaptor.Transformer`](/documentation/CreateMLComponents/EstimatorToTemporalAdaptor/fitted(to:eventHandler:)) Fits a transformer to a sequence of examples. [`typealias Input`](/documentation/CreateMLComponents/EstimatorToTemporalAdaptor/Input) The input type. [`typealias Output`](/documentation/CreateMLComponents/EstimatorToTemporalAdaptor/Output) The output type. [`typealias Transformer`](/documentation/CreateMLComponents/EstimatorToTemporalAdaptor/Transformer) The transformer type created by this estimator. ## Relationships ### Conforms To [`SendableMetatype`](/documentation/Swift/SendableMetatype) [`TemporalEstimator`](/documentation/CreateMLComponents/TemporalEstimator) [`Sendable`](/documentation/Swift/Sendable) --- Copyright © 2026 Apple Inc.
