An HTTP/3 error.

Variants

Done

There is no error or no work to do

BufferTooShort

The provided buffer is too short.

InternalError

Internal error in the HTTP/3 stack.

ExcessiveLoad

Endpoint detected that the peer is exhibiting behavior that causes. excessive load.

IdError

Stream ID or Push ID greater that current maximum was used incorrectly, such as exceeding a limit, reducing a limit, or being reused.

StreamCreationError

The endpoint detected that its peer created a stream that it will not accept.

ClosedCriticalStream

A required critical stream was closed.

MissingSettings

No SETTINGS frame at beginning of control stream.

FrameUnexpected

A frame was received which is not permitted in the current state.

FrameError

Frame violated layout or size rules.

QpackDecompressionFailed

QPACK Header block decompression failure.

TransportError(Error)

Error originated from the transport layer.

StreamBlocked

The underlying QUIC stream (or connection) doesn’t have enough capacity for the operation to complete. The application should retry later on.

SettingsError

Error in the payload of a SETTINGS frame.

RequestRejected

Server rejected request.

RequestCancelled

Request or its response cancelled.

RequestIncomplete

Client’s request stream terminated without containing a full-formed request.

MessageError

An HTTP message was malformed and cannot be processed.

ConnectError

The TCP connection established in response to a CONNECT request was reset or abnormally closed.

VersionFallback

The requested operation cannot be served over HTTP/3. Peer should retry over HTTP/1.1.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy 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)>

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

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
