Module: GraphWeaver::InputStruct

Includes:
Kernel
Defined in:
lib/graph_weaver/input_struct.rb

Overview

Runtime for generated input structs. Each struct declares its typed consts plus a compact FIELDS table — (prop, wire name, requiredness, serializer, coercer) per field, with the conversions emitted as lambdas — and this module is the loop that drives it. One copy here instead of unrolled methods in every struct, which is the difference between ~2 lines and ~6 lines per field when a Hasura bool_exp pulls hundreds of input types into one module.
