Trait Implementations

impl<TE: Clone> Clone for Error<TE>

fn clone(&self) -> Error<TE>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<TE: Debug> Debug for Error<TE>

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

Formats the value using the given formatter.

impl<TE> Display for Error<TE>

where TE: Display,

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

Formats the value using the given formatter.

impl<TE> Error for Error<TE>

where Self: Debug + Display,

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<Error> for Error<Error>

Available on crate feature libusb only.

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<TransferError> for Error<TransferError>

Available on crate feature nusb only.

fn from(value: TransferError) -> Self

Converts to this type from the input type.

impl<TE> From<UsbOperationError> for Error<TE>

fn from(source: UsbOperationError) -> Self

Converts to this type from the input type.

impl<TE: PartialEq> PartialEq for Error<TE>

fn eq(&self, other: &Error<TE>) -> 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.
