### notes:

1. easyjson use its own marshaler/unmarshaler, which is not tested

2. ujson use ujson.numeric which is its internal type for numbers

3. ugorji need to be configured in order to be compatible with standard library

4. 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

5. gjson deprecated its unmarshal methods from `v1.4.0`

6. gjson only decode into structure fields with tag (`<= v1.3.6`)
