Enum ClusterError 

#[non_exhaustive]
pub enum ClusterError {
    PeerNotFound {
        idx: u32,
    },
    CannotRemoveLocal,
    PeerAlreadyExists {
        addr: String,
    },
    Invalid(String),
}

Errors produced by the cluster admin layer.

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.

PeerNotFound

No peer in the pool has the requested index.

Fields

idx: u32

Index that was not found.

CannotRemoveLocal

The local peer cannot leave the cluster through the admin surface; the operator should stop the node instead.

PeerAlreadyExists

The supplied join target already exists in the peer list.

Fields

addr: String

host:port of the duplicate target.

Invalid(String)

Generic precondition failure (an Add change with no peer field, a Remove change with no peer_idx, …).

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.
