Enum TransferError 

pub enum TransferError {
    Cancelled,
    Stall,
    Disconnected,
    Fault,
    InvalidArgument,
    Unknown(u32),
}

Transfer error.

Variants

Cancelled

Transfer was cancelled or timed out.

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 Endpoint::clear_halt. For control requests, the stall is automatically cleared when another request is submitted.

Disconnected

Device disconnected.

Fault

Hardware issue or protocol violation.

InvalidArgument

The request has an invalid argument or is not supported by this OS.

Unknown(u32)

Unknown or OS-specific error.

It won’t be considered a breaking change to map unhandled errors from Unknown to one of the above variants. If you are matching on the OS-specific code because an error is not correctly mapped, please open an issue or pull request.

Trait Implementations

impl Clone for TransferError

fn clone(&self) -> TransferError

Returns a duplicate 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)>

Returns 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

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.
