pub fn path(&self) -> &Path

Trait Implementations

impl AuditLog for FileAuditLog

fn append<'life0, 'async_trait>( &'life0 self, event: Event, ) -> Pin<Box<dyn Future<Output = AuditResult<EventReceipt>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Append an event to the log. Returns a receipt the caller can keep as proof the event is recorded (contains event id + chain head at the time of append).

fn current_head<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = AuditResult<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The current chain head: hex-encoded hash of the last appended event, or the genesis sentinel if the log is empty.

fn verify_chain<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = AuditResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Replay the full chain, verifying every stored hash against the canonical bytes of the event. Returns Ok(()) if the chain is intact; errors identify the first event at which verification failed.

fn len<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = AuditResult<u64>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Total number of events appended since genesis.

impl Debug for FileAuditLog

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

Formats the value using the given formatter.
