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.
§

### Parse

The parser failed to parse the server response.

§

### AuthenticationFailed

The authentication with the server failed.

§

### UnexpectedReturnType

Operation failed because of a type mismatch.

§

### InvalidClientConfig

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

§

### Io

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.

§

### Client

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

§

### Extension

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

§

### MasterNameNotFoundBySentinel

Requested name not found among masters returned by the sentinels

§

### NoValidReplicasFoundBySentinel

No valid replicas found in the sentinels, for a given master name

§

### EmptySentinelList

At least one sentinel connection info is required

§

### ClusterConnectionNotFound

Used when a cluster connection cannot find a connection to a valid node.

§

### Server(ServerErrorKind)

An error returned from the server

§

### Serialize

Available on crate feature `json` only.

Error Serializing a struct to JSON form

§

### RESP3NotSupported

Redis Servers prior to v6.0.0 doesn’t support RESP3. Try disabling resp3 option
