#initialize(scalar_type) ⇒ Scalar

takes a resolved ScalarType — the generator picks it from the client-scoped overlay or the global registry

def coerce(expr) = @scalar.coerce_input(expr)

#coerce? ⇒ Boolean

coercion (opt-in per scalar): accept the value or its raw input and normalize before serializing — parse for a rich type (coerce: true), or a plain conversion for built-ins (coerce: :to_f). See ScalarType.

Returns:

  • (Boolean)

#hash_coerce(expr, _depth) ⇒ Object

inside input-struct hashes, scalars coerce exactly like variable kwargs do — the registry (incl. GraphWeaver.auto_coerce) decides
