Enum nusb::transfer::TransferError

pub enum TransferError {
    Cancelled,
    Stall,
    Disconnected,
    Fault,
    Unknown,
}

Transfer error.

Variants

Cancelled

Transfer was cancelled.

Stall

Endpoint in a STALL condition.

This is used by the device to signal that an error occurred. For bulk and interrupt endpoints, the stall condition can be cleared with Interface::clear_halt. For control requests, the stall is automatically cleared when another request is submitted.

Disconnected

Device disconnected.

Fault

Hardware issue or protocol violation.

Unknown

Unknown or OS-specific error.

Trait Implementations

impl Clone for TransferError

fn clone(&self) -> TransferError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransferError

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

Formats the value using the given formatter.

impl Display for TransferError

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

Formats the value using the given formatter.

impl Error for TransferError

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, request: &mut Request<'a>)

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

Provides type based access to context intended for error reports.

impl From<TransferError> for Error

fn from(value: TransferError) -> Self

Converts to this type from the input type.

impl PartialEq for TransferError

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

This method tests for self and other values to be equal, and is used by ==.

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

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