Struct AssignmentRecoveryDecision 

Source 
pub struct AssignmentRecoveryDecision {
    pub predecessor: CheckpointAssignmentFence,

Expand description

Immutable authorization to install one staged failure-recovery assignment.

Fields§

§predecessor: CheckpointAssignmentFence

Exact assignment being replaced.

§target: CheckpointAssignmentFence

Exact successor assignment authorized for installation.

§proposal: AssignmentSnapshotRef

Content-addressed staged snapshot whose assignment must equal target.

§removed_process_fences: Vec<ProcessLeaseFence>

Exact process-lease takeover proofs for every predecessor process absent from target.

§leader_proof: LeaderProof

Durable leader term that authorized this recovery.

Implementations§
