Expand description

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.
