}

Errors that can occur during cluster operations.

Variants

SlotNotAssigned(u16)

The slot is not assigned to any node.

Moved

The key belongs to a slot on a different node.

Fields

slot: u16

addr: SocketAddr

Ask

The slot is being migrated; client should retry with ASK.

Fields

slot: u16

addr: SocketAddr

NodeNotFound(NodeId)

Node not found in the cluster.

ClusterDown

Cluster is not in a healthy state.

WrongRole

Operation requires a different node role.

Fields

role: String

CrossSlot(u16, u16)

Cross-slot operation with keys in different slots.

Network(String)

Network error during cluster communication.

Timeout

Timeout waiting for cluster operation.

Configuration(String)

Configuration error.

Implementations

impl ClusterError

pub fn is_redirect(&self) -> bool

Returns true if this is a redirect error (MOVED or ASK).

pub fn moved(slot: u16, addr: SocketAddr) -> Self

Creates a MOVED error for a slot redirect.

pub fn ask(slot: u16, addr: SocketAddr) -> Self

Creates an ASK error for a slot migration redirect.

Trait Implementations

impl Debug for ClusterError

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

Formats the value using the given formatter.

impl Display for ClusterError

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

Formats the value using the given formatter.

impl Error for ClusterError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
