Variants

OutOfCapabilities

The size of the data being transferred exceeds the DFU capabilities.

InvalidState

Fields

got: State

expected: State

The device is in an invalid state (got: {got:?}, expected: {expected:?}).

BufferTooBig

Fields

got: usize

expected: usize

Buffer size exceeds the maximum allowed.

MaximumTransferSizeExceeded

Maximum transfer size exceeded.

EraseLimitReached

Erasing limit reached.

MaximumChunksExceeded

Maximum number of chunks exceeded.

NoSpaceLeft

Not enough space on device.

UnrecognizedStatusCode(u8)

Unrecognized status code: {0}

UnrecognizedStateCode(u8)

Unrecognized state code: {0}

ResponseTooShort

Fields

got: usize

expected: usize

Device response is too short (got: {got:?}, expected: {expected:?}).

StatusError(Status)

Device status is in error: {0}

StateError(State)

Device state is in error: {0}

UnknownProtocol

Unknown DFU protocol

InvalidInterfaceString

Failed to parse dfuse interface string

MemoryLayout(Error)

Failed to parse dfuse address from interface string

InvalidAddress

Failed to parse dfuse address from interface string

Trait Implementations

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, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.
