Our extensive benchmarks show us outperforming Gob, - Json, Bson, etc by 2-4X. - - Careful selected use of 'unsafe' for targeted performance gains. - - 100% safe mode supported, where 'unsafe' is not used at all. - - Lock-free (sans mutex) concurrency for scaling to 100's of cores - - In-place updates during decode, with option to zero value in maps and slices - prior to decode - - Coerce types where appropriate e.g. decode an int in the stream into a - float, decode numbers from formatted strings, etc - - Corner Cases: Overflows, nil maps/slices, nil values in streams are handled - correctly - - Standard field renaming via tags - - Support for omitting empty fields during an encoding - - Encoding from any value and decoding into pointer to any value (struct, - slice, map, primitives, pointers, interface{}, etc) - - Extensions to support efficient encoding/decoding of any named types - - Support encoding.(Binary|Text)(M|Unm)arshaler interfaces - - Support using existence of `IsZero() bool` to determine if a value is a zero - value. Analogous to time.Time.IsZero() bool. - - Decoding without a schema (into a interface{}). Includes Options to - configure what specific map or slice type to use when decoding an encoded - list or map into a nil interface{} - - Mapping a non-interface type to an interface, so we can decode appropriately - into any interface type with a correctly configured non-interface value. - - Encode a struct as an array, and decode struct from an array in the data - stream - - Option to encode struct keys as numbers (instead of strings) (to support - structured streams with fields encoded as numeric codes) - - Comprehensive support for anonymous fields - - Fast (no-reflection) encoding/decoding of common maps and slices - - Code-generation for faster performance, supported in go 1.6+ - - Support binary (e.g. messagepack, cbor) and text (e.g. json) formats - - Support indefinite-length formats to enable true streaming (for formats - which support it e.g. json, cbor) - - Support canonical encoding, where a value is ALWAYS encoded as same - sequence of bytes. This mostly applies to maps, where iteration order is - non-deterministic. - - NIL in data stream decoded as zero value - - Never silently skip data when decoding. User decides whether to return an - error or silently skip data when keys or indexes in the data stream do not - map to fields in the struct. - - Detect and error when encoding a cyclic reference (instead of stack overflow - shutdown) - - Encode/Decode from/to chan types (for iterative streaming support) - - Drop-in replacement for encoding/json. `json:` key in struct tag supported. - - Provides a RPC Server and Client Codec for net/rpc communication protocol. - - Handle unique idiosyncrasies of codecs e.g. For messagepack, - configure how ambiguities in handling raw bytes are resolved and provide - rpc server/client codec to support msgpack-rpc protocol defined at: - https://github.com/msgpack-rpc/msgpack-rpc/blob/master/spec.md - -# Extension Support - -Users can register a function to handle the encoding or decoding of their custom -types. - -There are no restrictions on what the custom type can be. Some examples: - -```go - type BisSet []int - type BitSet64 uint64 - type UUID string - type MyStructWithUnexportedFields struct { a int; b bool; c []int; } - type GifImage struct { ... } -``` - -As an illustration, MyStructWithUnexportedFields would normally be encoded as -an empty map because it has no exported fields, while UUID would be encoded as a -string. However, with extension support, you can encode any of these however you -like. - -There is also seamless support provided for registering an extension (with a -tag) but letting the encoding mechanism default to the standard way. - -# Custom Encoding and Decoding - -This package maintains symmetry in the encoding and decoding halfs. We determine -how to encode or decode by walking this decision tree - - - is there an extension registered for the type? - - is type a codec.Selfer? - - is format binary, and is type a encoding.BinaryMarshaler and - BinaryUnmarshaler? - - is format specifically json, and is type a encoding/json.Marshaler and - Unmarshaler? - - is format text-based, and type an encoding.TextMarshaler and - TextUnmarshaler? - - else we use a pair of functions based on the "kind" of the type e.g. map, - slice, int64, etc - -This symmetry is important to reduce chances of issues happening because the -encoding and decoding sides are out of sync e.g. decoded via very specific -encoding.TextUnmarshaler but encoded via kind-specific generalized mode. - -Consequently, if a type only defines one-half of the symmetry (e.g. -it implements UnmarshalJSON() but not MarshalJSON() ), then that type doesn't -satisfy the check and we will continue walking down the decision tree. - -# RPC - -RPC Client and Server Codecs are implemented, so the codecs can be used with the -standard net/rpc package. - -# Usage - -The Handle is SAFE for concurrent READ, but NOT SAFE for concurrent -modification. - -The Encoder and Decoder are NOT safe for concurrent use. - -Consequently, the usage model is basically: - - - Create and initialize the Handle before any use. Once created, DO NOT modify - it. - - Multiple Encoders or Decoders can now use the Handle concurrently. They only - read information off the Handle (never write). - - However, each Encoder or Decoder MUST not be used concurrently - - To re-use an Encoder/Decoder, call Reset(...) on it first. This allows you - use state maintained on the Encoder/Decoder. - -Sample usage model: - -```go - // create and configure Handle - var ( - bh codec.BincHandle - mh codec.MsgpackHandle - ch codec.CborHandle - ) - - mh.MapType = reflect.TypeOf(map[string]interface{}(nil)) - - // configure extensions - // e.g. for msgpack, define functions and enable Time support for tag 1 - // mh.SetExt(reflect.TypeOf(time.Time{}), 1, myExt) - - // create and use decoder/encoder - var ( - r io.Reader - w io.Writer - b []byte - h = &bh // or mh to use msgpack - ) - - dec = codec.NewDecoder(r, h) - dec = codec.NewDecoderBytes(b, h) - err = dec.Decode(&v) - - enc = codec.NewEncoder(w, h) - enc = codec.NewEncoderBytes(&b, h) - err = enc.Encode(v) - - //RPC Server - go func() { - for { - conn, err := listener.Accept() - rpcCodec := codec.GoRpc.ServerCodec(conn, h) - //OR rpcCodec := codec.MsgpackSpecRpc.ServerCodec(conn, h) - rpc.ServeCodec(rpcCodec) - } - }() - - //RPC Communication (client side) - conn, err = net.Dial("tcp", "localhost:5555") - rpcCodec := codec.GoRpc.ClientCodec(conn, h) - //OR rpcCodec := codec.MsgpackSpecRpc.ClientCodec(conn, h) - client := rpc.NewClientWithCodec(rpcCodec) -``` - -# Running Tests - -To run tests, use the following: - -``` - go test -``` - -To run the full suite of tests, use the following: - -``` - go test -tags alltests -run Suite -``` - -You can run the tag 'codec.safe' to run tests or build in safe mode. e.g. - -``` - go test -tags codec.safe -run Json - go test -tags "alltests codec.safe" -run Suite -``` - -# Running Benchmarks - -``` - cd bench - go test -bench . -benchmem -benchtime 1s -``` - -Please see http://github.com/ugorji/go-codec-bench . - -# Caveats - -Struct fields matching the following are ignored during encoding and decoding - - - struct tag value set to - - - func, complex numbers, unsafe pointers - - unexported and not embedded - - unexported and embedded and not struct kind - - unexported and embedded pointers (from go1.10) - -Every other field in a struct will be encoded/decoded. - -Embedded fields are encoded as if they exist in the top-level struct, with some -caveats.
