Struct ChainVerification 

pub struct ChainVerification {
    pub checked: usize,
    pub tampered_events: usize,
    pub linkage_breaks: usize,
    pub unknown_schema: usize,
    pub breaks: Vec<ChainBreak>,
}

Result of verifying the integrity of an enforcement event chain.

Verification is a READ-SIDE check over already-recorded events: it never mutates the store and performs no network I/O. It is the inverse of the write-time hash contract — it recomputes each event’s hash AND re-checks the prev_hash linkage, so it detects both:

• content tampering — an event whose body was altered after recording while its stored event_hash was left untouched (a linkage-only check misses this, because the stored hashes still chain together); and
• linkage breaks — a deleted, inserted, or re-pointed event, where one event’s prev_hash no longer matches its predecessor’s event_hash.

A full from-genesis rewrite (every hash recomputed consistently) is not detectable here by design — that is the inherent limit of a local, externally-unanchored chain, and is addressed at the custody layer, not here.

Fields

checked: usize

Events whose hash was recomputed and compared (excludes unknown-schema).

tampered_events: usize

Events whose stored event_hash does not match a fresh compute_hash() — i.e. the content was altered after recording.

linkage_breaks: usize

Adjacent events where prev_hash does not match the predecessor’s event_hash. The earliest surviving event is never counted, so a legitimately retention-pruned prefix is not a break.

unknown_schema: usize

Events with a schema_version newer than this binary understands. Their canonical form cannot be reproduced, so they are reported, not verified.

breaks: Vec<ChainBreak>

Every located break, in seq order. Empty when the chain is intact.

Implementations

impl ChainVerification

pub fn is_valid(&self) -> bool

True only when the chain is fully intact and fully verifiable: no content tampering, no linkage breaks, and no events this binary cannot verify.

Trait Implementations

impl Clone for ChainVerification

fn clone(&self) -> ChainVerification

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainVerification

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

Formats the value using the given formatter.

impl Default for ChainVerification

fn default() -> ChainVerification

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChainVerification

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ChainVerification

impl PartialEq for ChainVerification

fn eq(&self, other: &ChainVerification) -> 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.

impl Serialize for ChainVerification

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
