Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

request_type: UsbRequestType

Whether the request is standard, class-specific or vendor-specific.

recipient: UsbRecipient

The target of the transfer on the device.

request: u8

Vendor-specific command.

value: u16

Vendor-specific request parameters.

index: u16

The interface number of the recipient.
