能否将 *[ ]interface{} 转 struct ？

func selectExe(sqlStr string,afterScan func(sct *[]interface{}),sctType interface{},args ...interface{})([]interface{},error){

    thisTx := getSqlTx()
    defer thisTx.Commit() 
    stmt, err := thisTx.Prepare(sqlStr)
    defer stmt.Close()

    if err != nil {
        log.Fatal(err)
        return nil,err
    }

    rows, err := stmt.Query(args...)
    if err != nil {
        log.Fatal(err)
        return nil,err
    }

    result := make([]interface{}, 0)
    s := reflect.ValueOf(sctType).Elem()
    length := s.NumField()
    oneRow := make([]interface{}, length)

    for i := 0; i < length; i++ {
        oneRow[i] = s.Field(i).Addr().Interface()
    }

    defer rows.Close()
    for rows.Next() {
        err := rows.Scan(oneRow...)
        afterScan(&oneRow) // 这一行
        if err != nil {
            panic(err)
        }
        result = append(result, s.Interface())
    }
    return result,nil
}

在上面的 afterScan 处，回调处理下面代码

func(sct *[]interface{}) {
                // 想要在这里把 sct 转为 postStruct 结构体，但是尝试了不行，求助啊！！！
        //post := (*sct).(postStruct)

}
