Module: Opencdd::Cddal::ValueSerializer

Defined in:
lib/opencdd/cddal/value_serializer.rb

Overview

Pure-function value serializer: converts AST value nodes into the CDDAL/Parcel wire string form. Extracted from Builder (TODO.impl/28) so the builder's property-assembly pipeline is a consumer of this module rather than owning the logic.

Stateless — safe to call from any context. The Builder mixes this in for backward compatibility.
