`ProtocolSelectError`

Fields

proto_name: Option<String>

`ProtocolError`

Fields

id: SessionId

Session id

proto_id: ProtocolId

Protocol id

error: Error

Codec error

Protocol error during interaction

`SessionTimeout`

Fields

session_context: Arc<SessionContext>

Session context

After initializing the connection, the session does not open any protocol, suspected fd attack

`MuxerError`

Fields

session_context: Arc<SessionContext>

Session context

error: Error

error, such as InvalidData

Multiplex protocol error

`ProtocolHandleError`

Fields

proto_id: ProtocolId

Protocol id

error: ProtocolHandleErrorKind

error

Protocol handle error, will cause memory leaks/abnormal CPU usage tentacle will close after this error output

`SessionBlocked`

Fields

session_context: Arc<SessionContext>

Session context

Session blocked, can’t send message, if the task is too heavy in a short time. such as too many data cache on this session and can’t send to remote, it may cause oom, so this session will be kill by tentacle

Judging condition: unsent message size > send buffer size set by the user, default 24m
