Enum ChainBreakKind 

pub enum ChainBreakKind {
    Linkage,
    Tampered,
    UnknownSchema,
}

The kind of integrity failure a ChainBreak records.

Variants

Linkage

prev_hash does not match the predecessor’s event_hash. Caused by a deleted/inserted/re-pointed event — or, most commonly on a busy store, a concurrent write that captured the same prev_hash (distinguishable by a near-zero gap between the break and its predecessor; see ChainBreak).

Tampered

The stored event_hash does not match a fresh compute_hash() — the event body was altered after recording.

UnknownSchema

The event’s schema_version is newer than this binary understands, so its canonical form cannot be reproduced for verification.

Trait Implementations

impl Clone for ChainBreakKind

fn clone(&self) -> ChainBreakKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainBreakKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChainBreakKind

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ChainBreakKind

impl PartialEq for ChainBreakKind

fn eq(&self, other: &ChainBreakKind) -> 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 ChainBreakKind

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
