Though JSON is a ubiquitous data format, it is not a very compact format suitable for data exchange, for instance over a network. Hence, the library supports
to efficiently encode JSON values to byte vectors and to decode such vectors.
| Format | Serialization | Deserialization |
|---|---|---|
| BSON | incomplete: top-level value must be an object | incomplete, but all JSON types are supported |
| CBOR | complete | incomplete, but all JSON types are supported |
| MessagePack | complete | complete |
| UBJSON | complete | complete |
| Format | Binary values | Binary subtypes |
|---|---|---|
| BSON | supported | supported |
| CBOR | supported | not supported |
| MessagePack | supported | supported |
| UBJSON | not supported | not supported |
See binary values for more information.
