# CBOR encoder for Go

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](http://ietf.org).

The [specification](http://tools.ietf.org/html/rfc7049)

has recently been approved as an IETF Standards-Track specification

and has been published as RFC 7049.

## Usage

```go

package main

import (

	"fmt"

	"cbor"

	"bytes"

)

//custom struct

type Vector struct {

	X, Y, Z int

	Range []Range

	Label string

}

type Range struct {

	Length int

	Align float32

}

func main() {

	v := &Vector {

		X: 10,

		Y: 15,

		Z: 100,

		Range: []Range{

			Range {1,10},

			Range {223432423,30},

			Range {3,41.5},

			Range {174,55555.2},

		},

		Label: "HoHoHo",

	}

	//create encoder and marshal

	var buffTest bytes.Buffer

	encoder := cbor.NewEncoder(&buffTest)

	ok, error := encoder.Marshal(v)

	//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)

}

```

## Compatibility

Checked with [PHP extension](https://github.com/2tvenom/CBOREncode) in encode and decode

## Known issues

- 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.
