The runtime evaluates compiled contracts against Arrow data and caller context. Use the pages below for public fields, method signatures, parameters, return values, and errors.

API	Main types and functions
Caller context	Caller, refusal, param_values, active_shapes.
Data validation	validate, validate_in, Verdict, selectivity, RuntimeError.
Result shapes	apply, Shaped, Charge, suppression helpers.
Comparing rule evaluators	differential, DiffReport, Mismatch.
CEL evaluation	Scope, context, eval, value conversion.

Validation

For validation signatures and returned fields, see Data validation. Loading and exporting compiled contracts are covered in Compiled artifacts and exports.

The default wasm feature enables WebAssembly functions. The optional substrait feature enables Substrait export.
