Custom Unmarshal not working

[Vingtoft]

Following this example, I have written the below code:

package main

import (
    "bytes"
    "fmt"

    "github.com/amzn/ion-go/ion"
)

func main() {
    UnmarshalCustomMarshaler()
}

type unmarshalMe struct {
    Name   string
    custom bool
}

func (u *unmarshalMe) UnmarshalIon(r ion.Reader) error {
    fmt.Print("UnmarshalIon called")
    u.custom = true
    return nil
}

func UnmarshalCustomMarshaler() {
    ionBinary, err := ion.MarshalBinary(unmarshalMe{
        Name: "John Doe",
    })
    if err != nil {
        fmt.Println("Error marshalling ion binary: ", err)
        panic(err)
    }

    dec := ion.NewReader(bytes.NewReader(ionBinary))
    var decodedResult unmarshalMe

    ion.UnmarshalFrom(dec, &decodedResult)
    fmt.Println("Decoded result: ", decodedResult)
}

Expected result is that u.custom is true, this is not the case: u.custom is false.

Is this a bug, or have i misunderstanded how to implement custom unmarshal?

Hi,

You should probably look at the version, you are using.
The latest version v1.1.3 does not contain the feature.

You are correct, thanks.

I've just released v1.2.0 which does contain the feature in #185.
