A QUIC error.

Variants

Done

There is no more work to do.

BufferTooShort

The provided buffer is too short.

UnknownVersion

The provided packet cannot be parsed because its version is unknown.

InvalidFrame

The provided packet cannot be parsed because it contains an invalid frame.

InvalidPacket

The provided packet cannot be parsed.

InvalidState

The operation cannot be completed because the connection is in an invalid state.

InvalidStreamState(u64)

The operation cannot be completed because the stream is in an invalid state.

The stream ID is provided as associated data.

InvalidTransportParam

The peer’s transport params cannot be parsed.

CryptoFail

A cryptographic operation failed.

TlsFail

The TLS handshake failed.

FlowControl

The peer violated the local flow control limits.

StreamLimit

The peer violated the local stream limits.

StreamStopped(u64)

The specified stream was stopped by the peer.

The error code sent as part of the STOP_SENDING frame is provided as associated data.

StreamReset(u64)

The specified stream was reset by the peer.

The error code sent as part of the RESET_STREAM frame is provided as associated data.

FinalSize

The received data exceeds the stream’s final size.

CongestionControl

Error in congestion control.

IdLimit

Too many identifiers were provided.

OutOfIdentifiers

Not enough available identifiers.

KeyUpdate

Error in key update.

CryptoBufferExceeded

The peer sent more data in CRYPTO frames than we can buffer.

InvalidAckRange

The peer sent an ACK frame with an invalid range.

OptimisticAckDetected

The peer send an ACK frame for a skipped packet used for Optimistic ACK mitigation.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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

Formats the value using the given formatter.

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

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<BufferTooShortError> for Error

fn from(_err: BufferTooShortError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(err: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
