Arrays cause encoding failure.

[aarondl]

It appears that arrays are not able to be serialized.

package main

import (
    "github.com/ugorji/go/codec"
    "bytes"
    "log"
)

type bstruct struct {
    B [3]byte
}

func main() {
    b := bstruct{
        [3]byte{5, 7, 8},
    }

    log.Println(b)

    var m codec.MsgpackHandle

    var buf bytes.Buffer
    encoder := codec.NewEncoder(&buf, &m)
    if err := encoder.Encode(b); err != nil {
        log.Fatal("Failed to encode:", err)
    }
}

This snippet produces:
2013/11/14 09:01:41 Failed to encode:reflect.Value.Slice: slice of unaddressable array

Are arrays not able to be serialized?

This one is kinda messed up.

The short answer is that I can support it, but it will involve duplicating code. Which is clearly a better option that not supporting.

The long answer:

• Not all arrays are addressable.
• An array which is a field in a non-addressable value is not addressable.

Consequently, in your example above, encoder.Encode(&b) will work, but encoder.Encode(b) will not.

The error happened because I wanted to eliminate code duplication, so when it was time to encode an array, I converted it to a slice and sent it to the kSlice method.

Clearly this is not robust, so I'd do the duplication and try to reduce code size in both.

Fix coming soon.

I don't have tests for non-addressable arrays (unfortunately). I'd add one.
