Struct ExecutionContext 

Source 
pub struct ExecutionContext<S: State> {
    pub state: S,
    pub field_versions: FieldVersionTracker,
    pub versions_seen: VersionsSeen,
    pub pending_writes: Vec<PendingWrite>,
}
Expand description

Mutable execution context: holds state and version tracking

Encapsulates the mutable portions of the Pregel loop that change during execution, separating them from the immutable configuration.

Fields§

§state: S

Current state

§field_versions: FieldVersionTracker

Field version tracker (equivalent to channel_versions)

§versions_seen: VersionsSeen

Versions seen by each node (equivalent to versions_seen)

§pending_writes: Vec<PendingWrite>

Pending writes for checkpoint recovery
