Enum RemovalRejection 

pub enum RemovalRejection {
    NotAMember {
        member: NodeIdentity,
    },
    NotDraining {
        member: NodeIdentity,
    },
    StillOwnsRanges {
        member: NodeIdentity,
        ranges: Vec<(CollectionId, RangeId)>,

}

Why a membership removal was refused. Every variant leaves both catalogs untouched — a planned removal fails closed while any dependency remains.

Variants

NotAMember

The node is not a member of this cluster.

Fields

member: NodeIdentity

NotDraining

The member has not been marked draining. Planned removal must mark a member Draining first (use MembershipCatalog::begin_drain); force-remove is the path for a member that was never drained.

Fields

member: NodeIdentity

StillOwnsRanges

The member still owns these ranges — removing it would orphan their write authority. Drain must hand them off first.

Fields

member: NodeIdentity

ranges: Vec<(CollectionId, RangeId)>

StillReplicaFor

The member still holds replica copies of these ranges — removing it would drop required copies. Drain must evacuate them first.

Fields

member: NodeIdentity

ranges: Vec<(CollectionId, RangeId)>

Trait Implementations

impl Clone for RemovalRejection

fn clone(&self) -> RemovalRejection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RemovalRejection

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

Formats the value using the given formatter.

impl Display for RemovalRejection

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

Formats the value using the given formatter.

impl Eq for RemovalRejection

impl Error for RemovalRejection

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 RemovalRejection

fn eq(&self, other: &RemovalRejection) -> 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.
