如何在Go lang中将Aerospike BinMap转换为结构数组？

I am reading all record set from aerospike set as below:

stmt :=  as.NewStatement(namespace, set)
recordSet, err := db.AerospikeClient.Query(nil,stmt)

now I want to map the result records to the struct of the set. How can I do that?

I tried mapping record.Bins to struct but it didn't worked. The result should be array of below struct:

type MyStruct struct {
  name           string     `as:"userId" json:"userId"`
  UserList  []UserList `as:"userList" json:"userList"`
  CreatedAt        int64      `as:"createdAt" json:"createdAt"`
  UpdatedAt        int64      `as:"updatedAt" json:"updatedAt"`
}

Here is the code that I tried:

for rec := range recordSet.Records {
    var myStruct MyStruct
    jsonString, err := json.Marshal(rec.Bins)
    if err != nil {
        utils.LogErr("","", "Error occurred while marshling all the records from old set to my struct", err)
        return nil, err
    }
    err = json.Unmarshal(jsonString,&myStruct)
}

It is giving below error:

"error":"json: unsupported type: map[interface {}]interface {}"
