Decoder/encoder from Go data to CBOR binary string. This code has been developed and maintained by Ven at March 2014.
CBOR is an object representation format defined by the IETF. The specification has recently been approved as an IETF Standards-Track specification and has been published as RFC 7049.
package main

type Vector struct {
X, Y, Z int
Range []Range
Label string
}
type Range struct {
Length int
Align float32

//create encoder and marshal
var buffTest bytes.Buffer

//check binary string
if !ok {
fmt.Errorf("Error decoding %s", error)
} else {
fmt.Printf("Variable Hex = % x\n", buffTest.Bytes())
fmt.Printf("Variable = %v\n", buffTest.Bytes())
}
fmt.Printf("-----------------\n")
//unmarshal binary string to new struct
var vd Vector
ok, err := encoder.Unmarshal(buffTest.Bytes(), &vd)
if !ok {
fmt.Printf("Error Unmarshal %s", err)
return
}
//output
fmt.Printf("%v", vd)
}Checked with PHP extension in encode and decode
- Not support tags. 6 major type (in future)
- Not support 16 floats encoding
- Not decode nil (null) vars
- Encode does't support indefinite-length values.
