Struct ActivityLogger 

pub struct ActivityLogger { /* private fields */ }

Activity logging service with optional disk persistence.

Implementations

impl ActivityLogger

pub fn new() -> Self

Create a new activity logger without persistence.

pub fn with_persistence(log_dir: PathBuf) -> Result<Self>

Create a new activity logger with persistence to the specified directory.

pub fn with_persistence_and_options( log_dir: PathBuf, max_log_size: u64, max_memory_entries: usize, ) -> Result<Self>

Create a new activity logger with persistence and custom options.

pub fn verify_integrity(&self) -> Result<usize, String>

Verify the integrity of all persisted audit logs. Returns Ok(record_count) if integrity is verified, Err with details otherwise.

Note: If old log files have been cleaned up due to rotation limits, the first remaining file’s first record will have a prev_hash that references the (now deleted) previous file. In this case, we accept the first record’s prev_hash as valid and continue verification from there.

pub fn verify_integrity_strict(&self) -> Result<usize, String>

Verify integrity with strict mode - requires chain to start from “genesis”. Use this for complete audit verification when all log files are present.

pub fn flush(&self) -> Result<()>

Force flush any buffered data to disk.

pub fn log(&self, activity_type: ActivityType, description: &str) -> String

Log a new activity.

pub fn log_query(&self, sql: &str, duration_ms: u64, user: Option<&str>)

Log a query activity with duration.

pub fn log_write(&self, description: &str, user: Option<&str>)

Log a write activity.

pub fn log_config(&self, description: &str, user: Option<&str>)

Log a configuration change.

pub fn log_node(&self, description: &str)

Log a node event.

pub fn log_auth(&self, description: &str, user: Option<&str>)

Log an authentication event.

pub fn log_system(&self, description: &str)

Log a system event.

pub fn log_with_details( &self, activity_type: ActivityType, description: &str, duration: Option<u64>, user: Option<&str>, source: Option<&str>, details: Option<Value>, ) -> String

Log an activity with full details.

pub fn get_recent(&self, limit: usize) -> Vec<Activity>

Get recent activities.

pub fn get_by_type( &self, activity_type: ActivityType, limit: usize, ) -> Vec<Activity>

Get activities by type.

pub fn get_by_user(&self, username: &str, limit: usize) -> Vec<Activity>

Get activities by user.

pub fn count(&self) -> usize

Get activity count.

pub fn clear(&self)

Clear all activities.

impl Default for ActivityLogger

fn default() -> Self

Returns the “default value” for a type.
