Enum RangeWriteReject 

pub enum RangeWriteReject {
    NoRange {
        collection: CollectionId,
    },
    NotOwner {
        collection: CollectionId,
        range_id: RangeId,
        role: RangeRole,
        owner: NodeIdentity,
    },
    StaleEpoch {
        collection: CollectionId,
        range_id: RangeId,
        expected: OwnershipEpoch,
        current: OwnershipEpoch,
    },
}

Why an ownership-aware public write was rejected (issue #990).

This is a routing/ownership error, deliberately distinct from the instance-wide read-only rejection raised by WriteGate: a replica/non-holder rejecting a public write is not “this node is read-only”, it is “this node is not the authority for this range — route to the owner”. Crucially, none of these rejections fall back to the privileged internal replica-apply path; a public write that is not for this node’s owned range never reaches storage.

Variants

NoRange

No range of the collection covers the routed key, so the write cannot be placed. The caller must (re)resolve routing against a fresher catalog.

Fields

collection: CollectionId

NotOwner

This node holds the range but is not its owner (a Replica), or holds no copy at all (NoCopy). Either way a public write must be routed to owner, never applied locally.

Fields

collection: CollectionId

range_id: RangeId

role: RangeRole

owner: NodeIdentity

StaleEpoch

This node is the range owner, but the write was authorised under an ownership epoch that no longer matches the catalog — a write fenced out because ownership has since moved (its epoch advanced). Carries both epochs so the caller can see how far the routing decision was behind.

Fields

collection: CollectionId

range_id: RangeId

expected: OwnershipEpoch

current: OwnershipEpoch

Trait Implementations

impl Clone for RangeWriteReject

fn clone(&self) -> RangeWriteReject

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RangeWriteReject

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

Formats the value using the given formatter.

impl Display for RangeWriteReject

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

Formats the value using the given formatter.

impl Eq for RangeWriteReject

impl Error for RangeWriteReject

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 RangeWriteReject

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