An opaque handle to a parsed JSON document.

Documents belong to the process that opened them. Use SimdJson.close/1 for deterministic cleanup; the wrapped native resource is intentionally not a public API. Inspection is lifecycle-neutral and reveals neither input nor native identity.

A document is a one-shot source for SimdJson.select/2. Once native cursor access begins, success or failure consumes it. Use another document or the binary form of SimdJson.select/2 for another projection; documents are not rewound or reparsed transparently.

iex> {:ok, document} = SimdJson.open(~s({"value":1}))
iex> inspect(document)
"#SimdJson.Document<opaque>"
iex> {:error, error} = SimdJson.select(document, value: ["missing"])
iex> {error.reason, error.path}
{:no_such_field, ["missing"]}
iex> SimdJson.close(document)
:ok
