Function ParseVMID

pkg/api/utils.go:260–273

ParseVMID extracts and validates a VM ID from various input types. This function handles the common scenario where VM IDs can come from different sources (JSON APIs, user input, etc.) in various formats. It safely converts the input to a valid integer VM ID. Supported input types: - int: Direct in

(input interface{})

//	vmid, err := ParseVMID("invalid")  // Returns 0, error
//	vmid, err := ParseVMID(-1)         // Returns 0, error
func ParseVMID(input interface{}) (int, error) {
	switch v := input.(type) {
	case int:
		return v, nil
	case float64:
		return int(v), nil
	case string:
		return strconv.Atoi(v)
	case nil:
		return 0, fmt.Errorf("VMID cannot be nil")
	default:
		return 0, fmt.Errorf("invalid VMID type: %T", input)
	}
}

// SafeStringValue safely converts various types to string representation.
