Struct CheckpointSealInventory 

pub struct CheckpointSealInventory {
    pub attempt: CheckpointAttempt,
    pub assignment_fence: Option<CheckpointAssignmentFence>,
    pub assignment_version: u64,
    pub required_vnodes: Vec<u32>,
    pub sealed_partials: Vec<SealedVnodePartial>,
    pub required_descriptors: Vec<String>,
    pub sealed_descriptors: Vec<SealedCommitDescriptor>,
}

Canonical artifact inventory bound into an immutable checkpoint seal.

A seal is meaningful only for the exact set that was proven durable. The inventory is exposed so recovery-side protocols (notably the designated external-sink committer) can independently validate the participant markers that the seal admitted.

Fields

attempt: CheckpointAttempt

Exact attempt named by the seal.

assignment_fence: Option<CheckpointAssignmentFence>

Exact cluster assignment certificate, or None for a local-runtime seal.

assignment_version: u64

Assignment generation attested by every vnode partial, including local-runtime seals.

required_vnodes: Vec<u32>

Sorted, duplicate-free vnode partials required by the seal.

sealed_partials: Vec<SealedVnodePartial>

Per-vnode writer, assignment-generation, length, and digest attestations.

required_descriptors: Vec<String>

Sorted, duplicate-free commit-descriptor keys required by the seal.

sealed_descriptors: Vec<SealedCommitDescriptor>

Per-descriptor writer, authority, length, and digest attestations.

Implementations

impl CheckpointSealInventory

pub fn sealed_descriptor(&self, key: &str) -> Option<&SealedCommitDescriptor>

Attestation for one exact descriptor key.

pub fn descriptor_leader_proof(&self) -> Result<Option<&LeaderProof>, String>

Exact leader term certified by every cluster descriptor in this seal.

An empty descriptor inventory has no descriptor authority. Local descriptors return None; a mixed, incomplete, or assignment-mismatched inventory is rejected.

Errors

Returns an error when the inventory is noncanonical, incomplete, or mixes authorities.
