Possible errors or other abnormal conditions.

Variants

EP0Stalled

EP Stalled after Setup packet. Not necessarily an error, the Device rejected EP transaction. Next request should clear Stall for EP0.

EP0NotEmptyAfterSetup

EP0 buffer is not empty after Setup packet was consumed.

EPWriteError

Can’t get how many bytes were written. Usually, this is some internal error.

EPReadError

Can’t get how many bytes were read. Usually, this is some internal error.

EPStalled

EP Stalled. Not necessarily an error, the Device rejected EP transaction.

EPReadFailed

Error while reading from the endpoint. No data or data limit reached. Usually, this is some internal error.

EP0BadGetStatusSize

Bad reply length for GET_STATUS control request. Length should be 2. Usually, this is some internal error.

EP0BadGetConfigSize

Bad reply length for GET_CONFIGURATION control request. Length should be 1. Usually, this is some internal error.

DataConversion

Failed to convert one data representation to another, e.g. with TryInto. Usually, this is some internal error.

SetAddressFailed

SET_ADDRESS didn’t work during Device setup. Usually, this is some internal error.

InvalidDescriptorLength

Descriptor length is larger than the size of data returned.

InvalidDescriptorType

Unexpected Descriptor type.

InvalidStringLength

String Descriptor length is odd.

UsbDeviceBuilder(BuilderError)

Wrapper for BuilderError of usb-device when UsbDeviceBuilder fails.

UserDefined1

User-defined meaning. Enum value is passed through, not used by the library.

UserDefined2

User-defined meaning Enum value is passed through, not used by the library.

UserDefinedU64(u64)

User-defined meaning Enum value is passed through, not used by the library.

UserDefinedString(String)

User-defined meaning Enum value is passed through, not used by the library.

Trait Implementations

impl Debug for AnyUsbError

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

Formats the value using the given formatter.

impl PartialEq for AnyUsbError

fn eq(&self, other: &AnyUsbError) -> 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.
