NEED_MORE if more input is needed, OK on success, or ERROR on failure.JsonStreamParser.tryParse
JsonStreamResult tryParse(out var value, out JsonError err) @safeAttempt to parse the buffered data as a single JSON root value.
Container roots (`{...}`, `[...]`) and closed scalars commit as soon as they are complete. A root-level number is only committed after finish has been called, because further digits could still arrive and extend the token; until then NEED_MORE is returned.
Parameters
value | Parsed value on OK; var.init otherwise. |
err | Populated on ERROR; JsonError.init otherwise. |
