Struct ResolvedSumTarget 

pub struct ResolvedSumTarget {
    pub target_collection: Option<String>,
    pub join_value: String,
    pub surrogate: Surrogate,
}

One resolved materialized-sum target: which row a (target collection, join value) pair names.

Produced on the Control Plane, where the primary-key → surrogate map lives, and consumed on the Data Plane, which never resolves anything itself.

Fields

target_collection: Option<String>

TARGET collection of the binding this entry was resolved for, or None for an entry lifted out of a replicated record written before the target collection travelled on the wire.

None matches ANY binding of the source by join value alone — exactly what such a record meant when it was written, and the only reading of it that keeps a node able to replay its own committed log across the upgrade. Nothing produces None at plan time.

join_value: String

Join-key value that names the target row.

surrogate: Surrogate

The target row’s stable cross-engine identity.

Implementations

impl ResolvedSumTarget

pub fn new( target_collection: impl Into<String>, join_value: impl Into<String>, surrogate: Surrogate, ) -> Self

The entry a binding’s resolution produces.

pub fn untargeted(join_value: impl Into<String>, surrogate: Surrogate) -> Self

An entry that names no target collection — see ResolvedSumTarget::target_collection. Only the replicated-record decoder builds these.

pub fn addresses(&self, target_collection: &str, join_value: &str) -> bool

Whether this entry answers for target_collection’s join_value.

pub fn matches_key(&self, key: &SumTargetKey) -> bool

Whether this entry answers for key.
