Expand description

Indicates the specific type/cause of a protocol error.

Variants§

§

WrongHttpMethod

Use of the wrong HTTP method (the WebSocket protocol requires the GET method be used).

§

WrongHttpVersion

Wrong HTTP version used (the WebSocket protocol requires version 1.1 or higher).

§

MissingConnectionUpgradeHeader

Missing Connection: upgrade HTTP header.

§

MissingUpgradeWebSocketHeader

Missing Upgrade: websocket HTTP header.

§

MissingSecWebSocketVersionHeader

Missing Sec-WebSocket-Version: 13 HTTP header.

§

MissingSecWebSocketKey

Missing Sec-WebSocket-Key HTTP header.

§

SecWebSocketAcceptKeyMismatch

The Sec-WebSocket-Accept header is either not present or does not specify the correct key value.

§

JunkAfterRequest

Garbage data encountered after client request.

§

CustomResponseSuccessful

Custom responses must be unsuccessful.

§

InvalidHeader(HeaderName)

Invalid header is passed. Or the header is missing in the request. Or not present at all. Check the request that you pass.

§

HandshakeIncomplete

No more data while still performing handshake.

§

HttparseError(Error)

Wrapper around a httparse::Error value.

§

SendAfterClosing

Not allowed to send after having sent a closing frame.

§

ReceivedAfterClosing

Remote sent data after sending a closing frame.

§

NonZeroReservedBits

Reserved bits in frame header are non-zero.

§

UnmaskedFrameFromClient

The server must close the connection when an unmasked frame is received.

§

MaskedFrameFromServer

The client must close the connection when a masked frame is received.

§

FragmentedControlFrame

Control frames must not be fragmented.

§

ControlFrameTooBig

Control frames must have a payload of 125 bytes or less.

§

UnknownControlFrameType(u8)

Type of control frame not recognised.

§

UnknownDataFrameType(u8)

Type of data frame not recognised.

§

UnexpectedContinueFrame

Received a continue frame despite there being nothing to continue.

§

ExpectedFragment(Data)

Received data while waiting for more fragments.

§

ResetWithoutClosingHandshake

Connection closed without performing the closing handshake.

§

InvalidOpcode(u8)

Encountered an invalid opcode.

§

InvalidCloseSequence

The payload for the closing frame is invalid.
