Possible errors resulting from ar-drivers API calls

Variants

IoError(Error)

A standard IO error happened. See std::io::Error for specifics

UsbError(Error)

An rusb error happened. See rusb::Error for specifics

HidError(HidError)

A hidapi error happened. See hidapi::HidError for specifics

SerialPortError(Error)

A serialport error happened. See serialport::Error for specifics

NotFound

No glasses were found.

PacketTimeout

Packet sending or reception timed out. Note that this is not the only timeout error that is sent (e.g. UsbError can contain a timeout), and also this is usually a fatal one.

Other(&'static str)

Other fatal error, usually a problem with the library itself, or a device support issue. File a bug if you encounter this.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

impl Error for Error

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
