Trait Implementations

impl Archive for UsbError

where usize: Archive, EhciError: Archive,

type Archived = ArchivedUsbError

The archived representation of this type.

type Resolver = UsbErrorResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <Self as Archive>::Resolver, out: Place<<Self as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl AsScalar<2> for UsbError

fn as_scalar(&self) -> [u32; 2]

impl Clone for UsbError

fn clone(&self) -> UsbError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UsbError

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<UsbError, __D> for Archived<UsbError>

where usize: Archive, <usize as Archive>::Archived: Deserialize<usize, __D>, EhciError: Archive, <EhciError as Archive>::Archived: Deserialize<EhciError, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<UsbError, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for UsbError

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

Formats the value using the given formatter.

impl Error for UsbError

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<EhciError> for UsbError

fn from(value: EhciError) -> Self

Converts to this type from the input type.

impl From<Error> for UsbError

fn from(value: Error) -> Self

Converts to this type from the input type.

impl From<UsbError> for usize

fn from(value: UsbError) -> Self

Converts to this type from the input type.

impl From<usize> for UsbError

fn from(value: usize) -> Self

Converts to this type from the input type.

impl FromScalar<2> for UsbError

fn from_scalar(value: [u32; 2]) -> Self

impl<__S: Fallible + ?Sized> Serialize<__S> for UsbError

where usize: Serialize<__S>, EhciError: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl Copy for UsbError
