What an Error is, independently of the command it belongs to.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Client(ClientError)

Raised if an error occurs within the driver

CacheWrongKeyType

Raised if a required cache key is in the wrong type

Aborted

A transaction has been aborted

Sentinel(String)

Raised if an error occurs when contacting Sentinel instances

Redis(RedisError)

Error returned by the Redis server

IO(Arc<Error>)

IO error when connecting the Redis server

Tls(Error)

Available on crate feature rustls only.

Raised by the TLS library

InvalidDnsName(Arc<InvalidDnsNameError>)

Available on crate feature rustls only.

Invalid Dns name (rustls)

Timeout(TimeoutKind)

A deadline expired before the operation completed

EOF

Raised when end of stream is reached

TokioJoin(Arc<JoinError>)

Available on crate feature tokio-runtime only.

Raised when a tokio join error occurs

OneshotCanceled(RecvError)

Raised when oneshot channel is canceled

MpscSend(SendError)

Raised when mpsc send error occurs

Utf8(Utf8Error)

Raised when UTF-8 error occurs

FromUtf8(FromUtf8Error)

Raised when FromUtf8 error occurs

ParseFloat(ParseFloatError)

Raised when parse float error occurs

ParseInt(ParseIntError)

Raised when parse int error occurs

TokioBroadcastSend(Arc<SendError<()>>)

Raised when tokio broadcast send error occurs

DisconnectedByPeer

Disconnected by peer

Trait Implementations

impl Clone for ErrorKind

fn clone(&self) -> Self

impl Error for ErrorKind

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
