Struct RoutingHint 

pub struct RoutingHint { /* private fields */ }

The routing information a non-owner hands back so the caller can reach the owner — the payload of both a forward (where to relay) and a redirect (where to retry).

It carries the owner’s NodeIdentity plus the OwnershipEpoch and CatalogVersion the decision was made at. The epoch/version let a topology-aware client tell stale hints from fresh ones and avoid retry loops against ownership that has since moved again (ADR 0037: routing “must consult ownership metadata with an epoch/version”).

Implementations

impl RoutingHint

pub fn collection(&self) -> &CollectionId

pub fn range_id(&self) -> RangeId

pub fn owner(&self) -> &NodeIdentity

pub fn epoch(&self) -> OwnershipEpoch

pub fn version(&self) -> CatalogVersion

Trait Implementations

impl Clone for RoutingHint

fn clone(&self) -> RoutingHint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoutingHint

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

Formats the value using the given formatter.

impl Display for RoutingHint

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

Formats the value using the given formatter.

impl Eq for RoutingHint

impl PartialEq for RoutingHint

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