Struct HashChain 

pub struct HashChain {
    pub prev_hash: [u8; 32],
    pub event_hash: [u8; 32],
    pub algorithm: HashAlgorithm,
}

Hash chain for tamper-evident event log.

Each event in the chain contains a hash of the previous event, creating an immutable, verifiable audit trail.

Fields

prev_hash: [u8; 32]

Hash of previous event (creates chain). Genesis event has zero prev_hash.

event_hash: [u8; 32]

Hash of this event (canonical serialization)

algorithm: HashAlgorithm

Algorithm used for hashing

Trait Implementations

impl Clone for HashChain

fn clone(&self) -> HashChain

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ComposeSchema for HashChain

fn compose(generics: Vec<RefOr<Schema>>) -> RefOr<Schema>

impl Debug for HashChain

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

Formats the value using the given formatter.

impl Default for HashChain

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HashChain

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HashChain

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSchema for HashChain

fn name() -> Cow<'static, str>

Return name of the schema.

fn schemas(schemas: &mut Vec<(String, RefOr<Schema>)>)

Implement reference [utoipa::openapi::schema::Schema]s for this type.

impl Copy for HashChain

impl Eq for HashChain

impl StructuralPartialEq for HashChain
