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(Error),
}

Error type

Many of the errors are wrappers around rusb::Error, 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(Error)

Implementations

impl Error

pub fn usb_stack_error(&self) -> Option<&RusbError>

Returns the underlying USB stack error if applicable.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
