Module: Canon::JsonParsing

Defined in:
lib/canon/json_parsing.rb

Overview

The only place canon talks to a JSON engine. The yeptris fast path (fused C-API materializer) engages through Yeptris::JSON.load — the strict JSON surface pinned to exact JSON.parse semantics upstream; without the native materializer the stdlib parser serves, unchanged. Errors normalize to JSON::ParserError so canon's rescues hold on both engines.
