Enum FenceReason 

pub enum FenceReason {
    Unleased,
    Revoked,
    TermSuperseded {
        lease_term: SupervisorTerm,
        current_term: SupervisorTerm,
    },
    EpochSuperseded {
        lease_epoch: OwnershipEpoch,
        current_epoch: OwnershipEpoch,

    Expired {

        expires_at_ms: u64,
    },
}

Why a range owner is self-fenced — the cause that revoked its durable-write authority. Reported by LeasedOwner::evaluate and carried in every durable-write rejection so an operator (or the owner’s own logs) can see which binding lapsed.

Variants

Unleased

The owner holds no lease at all (never granted one, or it was dropped). Catalog ownership without a lease is not authority to write.

Revoked

The Supervisor explicitly revoked the lease before its window closed — e.g. ahead of a planned ownership handoff.

TermSuperseded

The lease was granted under an older Supervisor term than the current one: a new Supervisor leader has been elected, so the lease no longer matches.

Fields

lease_term: SupervisorTerm

current_term: SupervisorTerm

EpochSuperseded

The lease’s ownership epoch no longer matches the range’s current epoch: ownership has moved via a transition, fencing this (now stale) owner.

Fields

lease_epoch: OwnershipEpoch

current_epoch: OwnershipEpoch

Expired

The lease’s validity window has closed at the current time. With the Supervisor partitioned away the owner cannot renew, so it stops writing the moment the lease lapses.

Fields

now_ms: u64

expires_at_ms: u64

Trait Implementations

impl Clone for FenceReason

fn clone(&self) -> FenceReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FenceReason

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

Formats the value using the given formatter.

impl Display for FenceReason

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

Formats the value using the given formatter.

impl Eq for FenceReason

impl Error for FenceReason

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 FenceReason

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