Enum DispatchPlan 

pub enum DispatchPlan {
    LocalDatastore,
    Replicas {
        targets: Vec<ReplicaTarget>,
        consistency: ConsistencyLevel,
    },
    NoTargets,
    Drop,
}

Dispatch plan produced by the cluster dispatcher.

LocalDatastore is the early-return branch the reference engine takes when the routing tag is ROUTING_LOCAL_NODE_ONLY (or when the request is destined for the local node and the topology has only one peer); the per-connection driver then hands the request off to its server-side connection pool.

Variants

LocalDatastore

Hand the request straight to the local datastore.

Replicas

Forward to one or more peer replicas. The carried consistency level is the one the planner resolved for this request (after applying any bucket-type override), so the dispatcher’s reply coalescer does not have to re-resolve it.

Fields

targets: Vec<ReplicaTarget>

Replica peers the request must be routed to.

consistency: ConsistencyLevel

Resolved consistency level.

NoTargets

Reply with an error: the cluster has no quorum-eligible targets.

Drop

Drop the request (QUIT-style swallow).

Trait Implementations

impl Clone for DispatchPlan

fn clone(&self) -> DispatchPlan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DispatchPlan

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

Formats the value using the given formatter.

impl PartialEq for DispatchPlan

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