Struct EvidenceLedger 

pub struct EvidenceLedger { /* private fields */ }

Validated immutable evidence participant content.

The link collection is private: validated rows can be borrowed with EvidenceLedger::links or moved out with EvidenceLedger::into_links. Direct mutation is rejected by the compiler:

use graphforge_knowledge::EvidenceLedger;
let mut ledger = EvidenceLedger::default();
ledger.links.clear();

Implementations

impl EvidenceLedger

pub fn new(links: Vec<EvidenceLink>) -> Result<Self, KnowledgeError>

Validate, sort, and construct evidence content.

pub fn links(&self) -> &[EvidenceLink]

Borrow the validated evidence links in canonical order.

pub fn into_links(self) -> Vec<EvidenceLink>

Consume the ledger and return its validated evidence links in canonical order.

pub fn merge(&self, staged: &Self) -> Result<Self, KnowledgeError>

Merge staged links idempotently.

pub fn evidence_fingerprint( &self, evidence_uuid: Uuid, ) -> Result<[u8; 32], KnowledgeError>

Canonical fingerprint over normalized immutable content.

pub fn evidence_fingerprints( &self, ) -> Result<Vec<(Uuid, [u8; 32])>, KnowledgeError>

Compute canonical evidence fingerprints in one pass without UUID searches.

pub fn batch(&self) -> Result<RecordBatch, KnowledgeError>

Build the authoritative evidence Arrow batch.

pub fn from_batches(batches: &[RecordBatch]) -> Result<Self, KnowledgeError>

Decode authoritative Arrow batches and re-run every invariant.
