Expand description

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.

`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
