Enum ControlPlaneError 

pub enum ControlPlaneError {
    NotLeader {
        leader: Option<ClusterVoterIdentity>,
    },
}

Why an attempt to append to the control-plane log was refused.

Variants

NotLeader

The caller is not the current Supervisor leader. Only the elected leader is the normal writer for control-plane entries (PRD #987 user story 12); a follower that tries to append is told who the leader is (if known) so it can forward.

Fields

leader: Option<ClusterVoterIdentity>

The current leader, if this node knows one.

Trait Implementations

impl Clone for ControlPlaneError

fn clone(&self) -> ControlPlaneError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ControlPlaneError

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

Formats the value using the given formatter.

impl Display for ControlPlaneError

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

Formats the value using the given formatter.

impl Eq for ControlPlaneError

impl Error for ControlPlaneError

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.

impl PartialEq for ControlPlaneError

fn eq(&self, other: &ControlPlaneError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
