Struct AuditChain 

pub struct AuditChain { /* private fields */ }

A tamper-proof hash chain of audit events.

Each event’s prev_hash links to the SHA-256 hash of the preceding event, forming a chain. If any event is deleted or modified, the chain breaks.

Implementations

impl AuditChain

pub fn new() -> Self

pub async fn append(&self, event: AuditEvent) -> AuditEvent

Append an event to the chain, linking it to the previous event’s hash.

pub async fn verify(&self) -> Result<(), AuditError>

Verify the integrity of the entire chain.

Returns Ok(()) if the chain is intact, or an error describing the first integrity violation found.

pub async fn events(&self) -> Vec<AuditEvent>

Get a snapshot of all events in the chain.

pub async fn len(&self) -> usize

Get the number of events in the chain.

pub async fn is_empty(&self) -> bool

Check if the chain is empty.
