An enum of all error kinds.

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.

ResponseError

The server generated an invalid response.

AuthenticationFailed

The authentication with the server failed.

TypeError

Operation failed because of a type mismatch.

ExecAbortError

A script execution was aborted.

BusyLoadingError

The server cannot response because it’s loading a dump.

NoScriptError

A script that was requested does not actually exist.

InvalidClientConfig

An error that was caused because the parameter to the client were wrong.

Moved

Raised if a key moved to a different node.

Ask

Raised if a key moved to a different node but we need to ask.

TryAgain

Raised if a request needs to be retried.

ClusterDown

Raised if a redis cluster is down.

CrossSlot

A request spans multiple slots

MasterDown

A cluster master is unavailable.

IoError

This kind is returned if the redis error is one that is not native to the system. This is usually the case if the cause is another error.

ClientError

An error raised that was identified on the client before execution.

ExtensionError

An extension error. This is an error created by the server that is not directly understood by the library.

ReadOnly

Attempt to write to a read-only server
