Errors that can occur during parsing an HTTP/2 frame.

Variants

BadFrameSize

A length value other than 8 was set on a PING message.

MaxFrameSize

Frame size exceeded

TooMuchPadding

The padding length was larger than the frame-header-specified length of the payload.

TooManyHeaders(StreamId)

Headers frame contains too many headers

InvalidSettingValue

An invalid setting value was provided

InvalidPayloadLength

The payload length specified by the frame header was not the value necessary for the specific frame type.

InvalidPayloadAckSettings

Received a payload with an ACK settings frame

InvalidStreamId

An invalid stream identifier was provided.

This is returned if a SETTINGS or PING frame is received with a stream identifier other than zero.

MalformedMessage

A request or response is malformed.

InvalidDependencyId

An invalid stream dependency ID was provided

This is returned if a HEADERS or PRIORITY frame is received with an invalid stream identifier.

InvalidPreface

An invalid preface

UnexpectedPushPromise

Unexpected push promise

Continuation(FrameContinuationError)

Continuation related error

Hpack(DecoderError)

Failed to perform HPACK decoding

Trait Implementations

impl Clone for FrameError

fn clone(&self) -> FrameError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FrameError

impl Debug for FrameError

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

Formats the value using the given formatter.

impl Display for FrameError

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

Formats the value using the given formatter.

impl Eq for FrameError

impl Error for FrameError

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<DecoderError> for FrameError

fn from(source: DecoderError) -> Self

Converts to this type from the input type.

impl From<FrameContinuationError> for FrameError

fn from(source: FrameContinuationError) -> Self

Converts to this type from the input type.

impl From<FrameError> for ClientError

fn from(source: FrameError) -> Self

Converts to this type from the input type.

impl From<FrameError> for ConnectionError

fn from(source: FrameError) -> Self

Converts to this type from the input type.

impl<E> From<FrameError> for ServerError<E>

fn from(source: FrameError) -> Self

Converts to this type from the input type.

impl PartialEq for FrameError

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