Expand description
Error handling for command execution
Variants
Timeout
No response within expected time frame Is recommended to create a new client/connection in this case.
EncodingCommandFailed
Failed encoding TX command
ProtocolViolation
Received an invalid response violating the RESP protocol. Ideally this should never happen. The following causes are conceivable
- Bug in this library (e.g. incomplete implementation of RESP protocol)
- Redis server bug
- Network failure. As we are using TCP, only a network stack bug or other exotic causes (e.g. bit flip) is reasonable. Is recommended to create a new client/connection in this case.
InvalidFuture
Future is no longer valid. This happens on fatal problems like timeouts or faulty responses, on which message<->future mapping can no longer be guaranteed Is recommended to create a new client/connection in this case.
TcpError
Low level network error
TimerError
Upstream timer/clock failure
CommandResponseViolation
Received an unexpected response incompatible with the command specification
ErrorResponse(String)
Redis error response. Inner value is the error message received.
