Data Structures

voiage uses a small set of explicit data structures to keep method inputs and outputs serializable, inspectable, and stable across bindings.

Core contract

Section titled “Core contract”

The v3 contract uses Polars wide frames with ordered Float64 columns for the public tabular containers. Explicit strategy and parameter names preserve labels; Arrow/Parquet remains the cross-language interchange boundary.

Key structures

Section titled “Key structures”
  • ValueArray — net benefit array with structured round-trip helpers (from_polars() / to_polars())
  • DecisionAnalysis — analysis orchestration facade
  • Intervention — intervention definition
  • DecisionProblem — decision problem formulation
  • TrialDesign — trial design specification
  • ParameterSet — parameter set with round-trip helpers (from_polars() / to_polars())
