HOW

目标: Navigate JSON.load post-order proc reentrancy, parser non-streaming execution, duplicate key insertion order retention, and thread-isolated create_id state
包: json 2.9.1
符号: JSON.load
JSON.parse
JSON::Parser
JSON.create_id
JSON.create_id=
环境: ruby
创建时间: 2026-08-17T02:43:33Z

assert JSON.load invokes its proc in post-order depth-first traversal but ignores the proc return value, leaving parsed elements unchanged unless mutated in-place
assert JSON.load supports reentrant parsing inside the proc to deserialize embedded JSON strings into parent container structures
assert JSON::Parser parses only the initial document and raises JSON::ParserError on concatenated documents rather than streaming
assert JSON.parse duplicate key collisions update the value while preserving the original key's initial index in hash insertion order
assert JSON.create_id is isolated in Thread.current so mutating create_id in one thread does not alter addition instantiation in other threads
