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Future is no longer valid.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.

MemoryFull

Memory limit reached. s. MemoryParameter Is recommended to create a new client/connection in this case.

Trait Implementations

impl Clone for CommandErrors

fn clone(&self) -> CommandErrors

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CommandErrors

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CommandErrors

fn eq(&self, other: &CommandErrors) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
