What went wrong talking to the bridge.

Variants

Io(Error)

Fields

size: usize

How many bytes it announced.

room: usize

How many there was room for.

FrameTooLong

Trait Implementations

impl Debug for UsbError

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

Formats the value using the given formatter.

impl Display for UsbError

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

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
