切片的（整数）索引作为结构数组

Question

Is it possible in Go create array with where each element of array will be array of slices or structures.

Something like in PHP

    $a = [1=>"test", 2=>""]
    // in this example 2 is integer will be for GoLang?
    $a[2] = [ object, object, object ]

Can I do in Go something like ? I know about incorrect syntax.

   var a [int][]StructureName

   b := make([]StructureName, 0)
   b := append ( b, StructureName{a, b, c, d})
   b := append ( b, StructureName{e, f, g, h})

   a[0] = append (a[0][0], b)

`/*
[
1 => [
    ‘username1’, <-- string element
    ‘events’=>[ <-- array of structures
        object1, <-- structure
        object2, <-- structure
        object3 <-- structure
        ]
    ],
2 => [ <-- next record
    ‘username2’,
    ‘events’=>[
        object1,
        object2,
        object3
        ]
    ]
]
*/
`

You can use map and map it from int => interface{}.

package main

import (
    "fmt"
)

func main() {
    m := make(map[int]interface{})
    var x []interface{}
    x = append(x, "username")
    x = append(x, []int{3, 1, 3})
    m[1] = x
    fmt.Println(m)
}

Hope this helps.
