notes:
- easyjson use its own marshaler/unmarshaler, which is not tested
- ujson use ujson.numeric which is its internal type for numbers
- ugorji need to be configured in order to be compatible with standard library
- ugorji decode into structure:
- can decode into a structure with tag
- cannot decode into a structure without a tag unless all field names are as same as tag names
- use its own marshaler/unmarshaler (codec.Selfer) interface to decode structure
- gjson deprecated its unmarshal methods from
v1.4.0 - gjson only decode into structure fields with tag (
<= v1.3.6)
