Available on crate feature transport only.

Transport layer errors.

Variants

Frame(FrameError)

Frame parsing error.

Io(Error)

I/O error (socket operations).

AuthenticationFailed

Invalid AEAD tag - frame authentication failed. Per spec: silently drop, do not respond.

UnknownSession

Unknown session ID. Per spec: silently drop to prevent session enumeration.

NonceReplay

Nonce replay detected. Per spec: silently drop to prevent replay attacks.

NonceTooOld

Nonce too old (outside anti-replay window). Per spec: silently drop.

FrameTooSmall

Frame too small to be valid. Per spec: silently drop to prevent parsing exploits.

ConnectionTimeout

Connection has timed out.

MaxRetransmitsExceeded

Too many retransmissions, connection failed.

ConnectionClosed

Connection is closed.

AmplificationLimit

Anti-amplification limit reached.

MigrationRateLimited

Migration rate limited.

CounterExhaustion

Counter exhaustion - nonce counter overflow. This is a critical security error requiring session termination.

Implementations

impl TransportError

pub fn is_silent_drop(&self) -> bool

Check if this error should result in silent drop (no response sent).

Per 2-TRANSPORT.md, these errors should not generate any response to prevent information leakage to attackers.

pub fn is_fatal(&self) -> bool

Check if this error is fatal to the connection.

pub fn is_security_error(&self) -> bool

Check if this error is a security-related error.

Trait Implementations

impl Debug for TransportError

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

Formats the value using the given formatter.

impl Display for TransportError

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

Formats the value using the given formatter.

impl Error for TransportError

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.

impl From<Error> for TransportError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<FrameError> for TransportError

fn from(source: FrameError) -> Self

Converts to this type from the input type.
