MessagePack encoding for Golang
Supports:
- Primitives, arrays, maps, structs, time.Time and interface{}.
- Appengine *datastore.Key and datastore.Cursor.
- CustomEncoder/CustomDecoder interfaces for custom encoding.
- Extensions to encode type information.
- Renaming fields via
msgpack:"my_field_name". - Omitting individual empty fields via
msgpack:",omitempty"tag or all empty fields in a struct. - Map keys sorting.
- Encoding/decoding all structs as arrays or individual structs.
- Simple but very fast and efficient queries.
