Membership-admin failure modes.

Variants

NotLeader

Mutating op reached a follower; leader_admin_endpoint is the leader’s admin port when one is known.

Fields

leader_admin_endpoint: Option<String>

Unsupported

This driver does not support runtime membership changes.

NotMember(u64)

The referenced node is not a current member.

NotCaughtUp(u64)

A learner was asked to be promoted but had not caught up.

WouldLoseQuorum

The change would drop the cluster below a viable quorum.

Timeout

The change did not commit within the deadline.

Driver(String)

Wrapped driver error.

MembersBelowTarget

Format-activation gate rejection: at least one member can’t read the target. incapable lists (node_id, max_readable_version).

Fields

target: u8

incapable: Vec<(u64, u8)>

TargetOutOfRange

Format-activation target outside local binary’s readable range.

Fields

target: u8

min: u8

max: u8

MembershipChangedSinceGate

Format-activation apply-keyed no-op: membership changed since gate.

Fields

target: u8

Trait Implementations

impl Debug for AdminError

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

Formats the value using the given formatter.

impl Display for AdminError

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

Formats the value using the given formatter.

impl Error for AdminError

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.
