This is a binary unmarshaler with wire encoding that I made for learning purposes. DO NOT USE production！ The specification of the wire is as follows
- https://developers.google.com/protocol-buffers/docs/encoding
- https://developers.google.com/protocol-buffers/docs/proto3#scalar
bin, _ := hex.DecodeString("08b96010b292041801")
type wireMessage struct {
Int32 int32 `protowire:"1,0,int32,optional"`
Int64 int64 `protowire:"2,0,int64,optional"`
Boolean bool `protowire:"3,0,bool,optional"`
}
var wm wireMessage
protowire.Unmarshal(bin, &wm)
fmt.Printf("%+v", wm)
// -> {Int32:12345 Int64:67890 Boolean:true}playground: https://play.golang.org/p/tdJvZhdYpcx
| Type | Meaning | Implemented |
|---|---|---|
| 0 | Varint | int32, int64, uint32, uint64, sint32, sint64, bool, |
| 1 | 64-bit | fixed64, sfixed64, double |
| 2 | Length-delimited | string, bytes, embedded messages, packed repeated fields |
| 5 | 32-bit | fixed32, sfixed32, float |
- oneof
- optional(The optional in proto3 is passed as an oneof value from the protoc compiler, so if We have already implemented oneof, We have actually implemented the optional.)
- embedded
- packed repeated
- unpacked repeated
