GO 基础获取类型大小

为什么80%的码农都做不了架构师？>>>

 

func intDataSize(data interface{}) int {
	switch data := data.(type) {
	case bool, int8, uint8, *bool, *int8, *uint8:
		return 1
	case []int8:
		return len(data)
	case []uint8:
		return len(data)
	case int16, uint16, *int16, *uint16:
		return 2
	case []int16:
		return 2 * len(data)
	case []uint16:
		return 2 * len(data)
	case int32, uint32, *int32, *uint32:
		return 4
	case []int32:
		return 4 * len(data)
	case []uint32:
		return 4 * len(data)
	case int64, uint64, *int64, *uint64:
		return 8
	case []int64:
		return 8 * len(data)
	case []uint64:
		return 8 * len(data)
	}
	return 0
}
