切片操作
-
Convertor
- 从 []T1 转换为 []T2，比如将 []string 转化为 []int。
-
Find
- 从切片中查找符合条件的子集，返回一个新的切片。
- 派生出来的有 First、FirstInt、FirstString 等，返回符合条件的第一个元素。
-
IndexOf
- 从切片中查找符合条件的第一个元素的索引
- 派生出来的有 IndexOfInt、IndexOfString、IndexOfInt64 等。
-
Remove/RemoveAt
- 从切片中删除符合条件的元素，并返回新的切片。
-
Repeat
- 重复一个对象N次，形成一个切片数组。循环过程中可以通过自定义函数控制生成的对象。
- 派生出来的有 RepeatInt、RepeatString 等。

Example ¶
arr := make([]interface{}, 4)
for i := range arr {
arr[i] = int64(i)
}
// 下面代码将会 Panic，因为无法从 []interface{} 直接转换为 []int64，即使切片内的元素类型相同。
// intArr := arr.([]int64)
// 通过 ToType(dstType=typeof(int64)) 可以实现转换。
intArr, _ := ToType(arr, reflect.TypeOf(int64(0))).([]int64)
if len(arr) != len(intArr) {
panic("length not equal")
}
for i := range intArr {
if arr[i] != intArr[i] {
panic(fmt.Sprintf("val[%v] not equal", i))
}
}
