Expand description

A trait that defines how to extract a scalar value from a structured input type.

The ScalarProjector trait enables decoupling of scalar signal extraction from data structures, allowing structured or composite types (e.g., GPSSample, IMUReading, or SymbolicTime) to be mapped onto simple scalar values (e.g., f64, i64) for use in causal inference, thresholding, or signal comparison.

This is particularly useful in systems like DeepCausality, where reasoning operates over NumericalValues (e.g., f64) but data inputs may be structured or symbolic. By implementing ScalarProjector, you gain the ability to compose, test, and swap scalar extraction strategies without modifying the underlying data types.

§Associated Types

  • Input: The structured data type from which to extract a scalar (e.g., GPSSample)
  • Scalar: The scalar value extracted, which must implement ScalarValue (e.g., f64, i64)

§See Also

  • ScalarValue: A trait representing primitive scalar types
  • Causaloid: The core reasoning unit in DeepCausality that can consume projectors
