# HIDReportID A type to represent the report IDs of HID reports. ``` struct HIDReportID ``` ## Overview Report IDs are defined to be 1 byte in the HID specification, and can help identify the reports received from or sent to a device. Report IDs are optional. If a descriptor only has one report, a report ID is unnecessary. A report ID of 0 is invalid.
