Enum EhciError 

pub enum EhciError {
    InvalidCapsLen,
    EndpointNotOpen,
    InvalidAddress,
    Disconnected,
    DescriptorError,
    OutOfPoolItems,
    SetupUnsuccessful,
    Stalled,
    ControllerDisabled,
}

Main error type for the crate

Variants

InvalidCapsLen

The CAPS_LEN field of the Capability Registers was wrong. Possibly means that the controller is not powered, or the base address was wrong.

EndpointNotOpen

The specified endpoint was not opened (See [crate::controller::Controller::open_endpoint])

InvalidAddress

The address specified was out of range.

Disconnected

The addressed device is disconnected.

DescriptorError

The descriptor was malformed

OutOfPoolItems

Could not allocate a pool item for the transfer or async queue

SetupUnsuccessful

There was a fatal error during the setup process of the device

Stalled

The endpoint stalled the transfer

ControllerDisabled

The controller is disabled

Trait Implementations

impl Archive for EhciError

type Archived = ArchivedEhciError

The archived representation of this type.

type Resolver = EhciErrorResolver

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: <EhciError as Archive>::Resolver, out: Place<<EhciError 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 Clone for EhciError

fn clone(&self) -> EhciError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EhciError

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

Formats the value using the given formatter.

impl<__D> Deserialize<EhciError, __D> for <EhciError as Archive>::Archived

where __D: Fallible + ?Sized,

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

Deserializes using the given deserializer

impl From<EhciError> for UsbError

fn from(value: EhciError) -> Self

Converts to this type from the input type.

impl<__S> Serialize<__S> for EhciError

where __S: Fallible + ?Sized,

fn serialize( &self, serializer: &mut __S, ) -> Result<<EhciError 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 EhciError
