Overview

SerializerConfigLayer

Lightweight, validated container for per-serializer overrides defined via the DSL.

  • Backed by a plain Hash for cheap deep-merge later (see WriterContext).

  • Only keys from Config.members are allowed; unknown keys raise NoMethodError.

  • Supports flat setters/getters in the DSL (e.g., c.null_strategy = :nullable_and_optional).

  • Mutable only via the DSL; #to_h returns a frozen hash to prevent external mutation.

Rationale: we don’t allocate another Config here; this layer is merged on top of library/global/writer settings when computing the effective config.

  raise NoMethodError, "Unknown configuration key: '#{key}'" unless VALID_KEYS.include?(key)

  return @target_hash[key] = args.first if name.end_with?("=") && args.length == 1

  return @target_hash[key] if args.empty?
