Enum Error 

pub enum Error {
    DeviceNotFound,
    DfuStatus {
        status: Status,
        state: State,
    },
    DfuInvalidDeviceStatus,
    DfuSetAddressFailed(Status, State),
    UsbContext(Error),
    UsbDeviceEnumeration(Error),
    UsbDeviceOpen(Error),
    UsbKernelDriverDetach(Error),
    UsbClaimInterface(Error),
    UsbSetAltSetting(Error),
    UsbControlTransfer(TransferError),
}

Error type

Many of the errors are wrappers around nusb::Error and nusb::transfer::TransferError, and are often somewhat esoteric. Error::usb_stack_error() can be used to retrieve the underlying USB stack error for further analysis, or test whether the failure was a USB stack one.

Variants

DeviceNotFound

DFU Device not found

DfuStatus

DFU status error returned by device

Fields

status: Status

state: State

DfuInvalidDeviceStatus

Invalid DFU device status response

DfuSetAddressFailed(Status, State)

DFU set address pointer failed

UsbContext(Error)

UsbDeviceEnumeration(Error)

UsbDeviceOpen(Error)

UsbKernelDriverDetach(Error)

UsbClaimInterface(Error)

UsbSetAltSetting(Error)

UsbControlTransfer(TransferError)
