:mrdocs:

Decode into the specified `value`, of a (template parameter) `TYPE`, the JSON data read from the specified `stream` and using the specified `options`. `TYPE` shall be a `bdeat`‐compatible sequence, choice, or array type, or a `bdeat`‐compatible dynamic type referring to one of those types. Specifying a nullptr `options` is equivalent to passing a default‐constructed DecoderOptions in `options`. Return 0 on success, and a non‐zero value otherwise. Note that this operation internally buffers input from `stream`, and if decoding is successful, will attempt to update the input position of `stream` to the last unprocessed byte.
