Implementations

impl AuditLog

pub fn open(vault_dir: &Path) -> Option<Self>

Open (or create) the audit database at <vault_dir>/audit.db.

Returns None if the database can’t be opened — callers should treat this as “audit logging unavailable” and continue normally.

pub fn log( &self, operation: &str, environment: &str, key_name: Option<&str>, details: Option<&str>, )

Record an operation. Fire-and-forget — errors are silently ignored.

pub fn query( &self, limit: usize, since: Option<DateTime<Utc>>, ) -> Result<Vec<AuditEntry>>

Query recent audit entries.

• limit: maximum number of entries to return (most recent first).
• since: if provided, only return entries newer than this timestamp.

pub fn purge(&self, before: DateTime<Utc>) -> Result<usize>

Delete audit entries older than the given timestamp. Returns the number of entries deleted.

pub fn db_path(vault_dir: &Path) -> PathBuf

Return the path to the audit database (for testing/display).
