在Golang中为复杂的JSON数组创建结构

I have the following JSON array that I'm trying to convert to a struct.

[
    {
        "titel": "test 1",
        "event": "some value",
        "pair": "some value",
        "condition": [
            "or",
            [
                "contains",
                "url",
                "/"
            ]
        ],
        "actions": [
            [
                "option1",
                "12",
                "1"
            ],
            [
                "option2",
                "3",
                "1"
            ]
        ]
    }, {
        "titel": "test 2",
        "event": "some value",
        "pair": "some value",
        "condition": [
            "or",
            [
                "contains",
                "url",
                "/"
            ]
        ],
        "actions": [
            [
                "option1",
                "12",
                "1"
            ],
            [
                "option2",
                "3",
                "1"
            ]
        ]
    }
]

This is the struct I've got so far:

type Trigger struct {
    Event     string        `json:"event"`  
    Pair      string        `json:"pair"`   
    Actions   [][]string    `json:"actions"`
    Condition []interface{} `json:"condition"`
}

type Triggers struct {
    Collection []Trigger
}

However, this does not really cover the "Condition" part. Ideally id like to have a structure for that as well.
