Variants

Fidl(Error)

FIDL channel or proxy communication failure.

DriverStatus(i32)

Non-OK status code returned by the serial hardware driver.

EmptyRead

Empty byte vector returned during handshake read.

Eof

End-of-file reached when reading frames from the serial device.

Handshake(HandshakeError)

Protocol negotiation frame decoding or validation failure.

NoCommonProtocol

Host and target share no supported framing protocol version.

Io(Error)

Filesystem or I/O failure while discovering serial devices.

NonUtf8Path

Serial device directory entry path is not valid UTF-8.

NoSerialPorts

No usable serial ports found under /dev/class/serial.

WriteRetriesExhausted

Serial write failed after exhausting all retry attempts.

ResetRequested

Host sent a control reset or control channel close frame.

SessionIdChanged

Host initiated a new handshake with a different session ID.

AckChannelClosed

Internal ACK notification channel closed unexpectedly.

Frame(FrameError)

Frame encoding or validation failure.

RetransmissionLimit(RetransmissionLimitExceeded)

Go-Back-N retransmission attempts exceeded the protocol limit.

UnexpectedSeq(UnexpectedSeqError)

Received an unexpected sequence number while advancing the receiver window.

ChannelSend(String)

Internal mpsc channel send failure between bridge tasks.

RcsConnect(String)

Failed to connect to the target RCS Connector FIDL protocol.

Trait Implementations

impl Debug for TargetDriverError

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

Formats the value using the given formatter.

impl Display for TargetDriverError

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

Formats the value using the given formatter.

impl Error for TargetDriverError

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.
