Expand description

An enum of all error kinds.

Variants (Non-exhaustive)

This enum is marked as 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
