Struct ChainVerificationReport 

pub struct ChainVerificationReport {
    pub rows_checked: u64,
    pub chain_break: Option<i64>,
    pub signature_failures: Vec<i64>,
}

Outcome of a verify_chain pass over the signed_events table.

rows_checked counts every row the verifier walked. chain_break is Some(sequence) when the FIRST detected break happens — that row’s stored prev_hash does not equal SHA-256(canonical_chain_bytes(row N-1)), OR the row’s sequence is not the expected prior + 1 (gap / duplicate / non-monotonic jump). signature_failures records sequences whose Ed25519 signature did not verify against the supplied key set — the chain itself may still be intact even if individual signatures fail (defense-in-depth split).

Fields

rows_checked: u64

chain_break: Option<i64>

signature_failures: Vec<i64>

Implementations

impl ChainVerificationReport

pub fn chain_holds(&self) -> bool

true when the cross-row chain held end-to-end. Per-row signature failures are surfaced separately because they are a disjoint property (a chain break is structurally worse than a signature failure).

Trait Implementations

impl Clone for ChainVerificationReport

fn clone(&self) -> ChainVerificationReport

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChainVerificationReport

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ChainVerificationReport

impl PartialEq for ChainVerificationReport

fn eq(&self, other: &ChainVerificationReport) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
